The goals of the dissertation were to expand the understanding of the interactive effects of CO2 enrichment and O3 induced stress on wheat (Triticum aestivum)and corn (Zea mays). Field experiments were conducted at USDA Beltsville Agricultural Research Center during 1991 (wheat and corn)and 1992 (wheat). Crops were grown in open-top chambers supplied with charcoal filtered air (CF)or CF + 40 ppb O3 above ambient O3 concentration (7h day-1, 5 days week -1)having CO2 concentrations of ambient (350 ppm CO2)or + 150ppm CO2 (12h day-1). Wheat photosynthesis rates (PS)under enriched CO2 were stimulated by 11 83: and 7 83: in 1991 and 1992, respectively. High O3 exposures reduced wheat PS by 10 83: and 6 83: for 1991 and 1992, respectively. Interaction effects between the two gases on PS were not significant. Reductions in stomatal conductance (gs)were under both elevated CO2 and O3 concentrations with trends for further reductions when the two gases were mixed. Canopy reflectance was used to assess the seasonal aboserbed photosynthetically active radiation (APAR)which explained close to 50 83: of the final dry biomass variaton in wheat. Increases in dry biomass (12 83: ) and grain yields (21 83: ) were noted in wheat grown under enriched CO2. High O3 exposuresreduced by 20 83: at ambient CO2 but only by 7 83: under enriched CO2. Corn was less sensitive to treatments compared to wheat. Grain yield in corn was reduced by 11 83: for plants grown under high O3 at ambient CO2. Enriched CO2 alone had no effect on corn grain yield; however, CO2 enrichment under high O3 exposure partially compensated for the negative impact of )3 stress on grain yield. The results indicated that CO2 enrichment had a physiological beneficial effect in wheat (C3 crop)but not in corn (C4 crop). Increases in O3 concentrations reduced production of booth, wheat and corn. It is likely that stress induced by exposure to O3 in both crops will be reduced under increased atmospheric CO2 concentrations; however, maximal benefits in crop production in wheat in response to CO2 enrichment will not materialize under concomitant increases in tropospheric O3 concentration MFN: 980 1: SID/SCD 2: 6809 3: INPE-6809-PRE/3181 4: SRE 5: MC 6: am 7: [07] 10: Novo, Evlyn Marcia leao de Moraes 12: Water spectral libraries for the interpretation of image spectrometric data 14: 91-102 16: 20: 12 40: En 41: En 42: 53: Imaging Spectometry of the Terrestrial Environment 54: 14-15 Apr. <1993> 56: Orlando 57: USA 61: 64: <1993> 68: PRE 90: b 83: This paper reports the assessment or water reflectance spectra measured under comtrolled condition for analysis of the imaging spectrometry data of inland waters. The application lf imaging spectrometry to the study ofinland waters depends om better understanging of the optical properties of the water components. To increase this understanding a collection of water spectra has beeen measured under laboratory and ground controlle conditiond as a part of ab EOS interdisciplinary investigation. The radiometric measurement derived from those exprements id known as the Bidirectional Reflectance Function (BRDF). R was simulated using variations of a model derived from the two stream approximation of the radiative transfer equation (RTE)and compared to the BRIDF. BRDF was also measured"in situ"from a boat based spectrometer (BoaR)and from an helicopter based spectrometer (HelR). Modelled R ( MolR)laboratory measured BRDF (labR)and ground measured BRDF ( BoaR and HelR)were compared. They were aksi used to unmix the spectra of two different aquatic systems. Preliminary results show that at low chlorophyll and gilvin concentration, there is a good agreement betweem ModR and LabR, regardless of the model varition used. For both low and high inprganic matter concentration, the agreement between ModR and LabR is poor. All sets or data present the main features whidch characterize the high chlorophyll concentration reflectance spectra, bul the amount of reflectante by LabR and MordR is 50 times smaller than that measured in situ. When the different sets are used as inpit to unmixing algorithms they also yield differebt results 91: FDB-19910217 92: FDB-MLR MFN: 1012 1: SID/SCD 2: 6570 3: INPE-6570-PRE/2607 4: SRE 5: MC 6: am 7: [07] 10: Kux, Hermann Johann Heinrich 10: Ahern, Frank J. 10: Raney, R.K 12: The contribution of SAREX'92 (South American Radar Experiment)campaign to the evaluation of natural resources in tropical rainforests: first results from test site Acre, SW-Amazonia, Brazil 14: 53-59 20: 7 40: En 41: En 42: 53: Canadian Symposium on Remote Sensing, 16 54: 7-10 June <1993> 56: Quebec 57: Canada 58: DSM 61: 64: <1993> 68: PRE 90: b 83: In the framework of a Canada/Brasil Cooperation Project and with the financial support of both the European Space Agency (ESA)and the Canada Internacional Development Agency (CIDA),an airborne SAR-580 campaign to acquire C-band HH and VV radar data was undertaken during April 1992 in Brazilian Amazonia.The overall objective of SAREX 92 to acquire a C-band dataset, including satellite data products, to be used for the evalution of spaceborne C-band SAR data in tropical forest environments. Results of these investigations will be used to promete "SAR literacy" among professional and tecxhnical staff responsible for tropical forest management in Brazil.This paper presents first results of SAR data evalution from a test site im Acre, a State in Brazil.The use of geometrically and radiometrically corrected SAR images is described and related to the detection of forest types, deforestation practices for pasture and small settlements as well as other man-made features. Examples of different relief features ( dissction by drainage, erosion, topography, etc), depicted from SAR images, and their relationships with landuse and landuse planning are shown when applicabe. Based on the interpretation of wide swath images, treated to represent data fidelity expected from RADARSAT, covering a total area of 18000 Km2, it appears that RADARSAT data has an important monitoring potencial for this region. From the data, information on tropical deforestation,drainage networks, soils, and vegetaion may be obtained. With such information, development may be managed, to avoid many of the severe environmental problems which have previously occurred is this region. 91: FDB-19920217 92: FDB-MLR MFN: 1019 1: SID/SCD 4: SRE 5: MC 6: am 7: [07] 10: Rudorff, Bernardo Friedrich Theodor 12: Interactive effects of CO2, enrichment an O, stress on canopy reflectance and plant characteristics in winter wheat 14: 122 18: Agronomy Abstracts 40: En 41: En 42: 53: American Society of Agronomy. 1993 Annual Meeting 54: 07-12 nov. <1993> 56: Cincinnati 57: USA 58: DSR 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 83: Field experiments were conductes during the Spring of 1991 at USDA_BARC to evaluate the interactive effects of chronic O3 (40nl 1-1 abo ambient O3 concentrations)and CO2 enchment (500 1-1 of CO2)in wheoi grown in open top field chambers.

Em paises mais desenvolvidos ja se consegue conviver com a Cartografia Digital, ao passo que naqueles que ainda se encontram em desenvolvimento, como o Brasil, registra-se um esforco consideravel para se passar do dominio analogico ao digital. Ambos os casos, entretanto, apresentam como caracteristicas comuns a definicao de padroes para a representacao digital e, principalmente, a digitalizacao corno meio basico de geracao da informacao digital. Infelizmente, a digitalizacao tambem representa uma fonte de erros consideravel num SIG e deve, portanto, ser cuidadosamente analisada. A ideia de um numero consideravelmente grande de pontos para descrever uma linha digitalizada contrapoe-se a busca de arquivos que nao ocupem tanto espa‡o para armazena-los. A meio caminho surge a indagacao: quantos pontos sao realmente necessarios para descrever uma linha com a acuracia requerida?

Corn and wheat were grown in open top field chambers exposed to two levels of O, (charcoal-filtered air, and ambient air + 40nl/L of O3)and two levels of CO2 (ambient,and + 150 1/L of CO2)from initiation of plant growth until harvest. Leaf photosynthesis,leaf area index and canopy reflectance were measured weekly and above ground dry biomass and grain yields were measured after harvest. Ozone had a negative impact on both dcrops. Carbon dioxide had a positive effect on wheat and no change was observed for corn. For the combined effect of both gases, O3, and CO2, the negative impacts caused by O3, were typucally counteracted by the CO2 enrichment 91: FDB-19920310 92: FDB-MLR MFN: 3171 1: SID/SCD 2: 5422 3: INPE-5422-PRP/170 4: SRE 5: MP 6: m 7: [07] 16: Hernandez Filho, Pedro 16: Shimabukuro, Yosio Edemir 16: Lee, David Chung Liang 16: Santos Filho,Celio Paiva do 16: Almeida, Rionaldo Rolo de 18: Relatorio Final do projeto de inventario florestal na Floresta Nacional do Tapajos 20: 121 40: Pt 41: Pt 41: En 42: E 58: DSR 59: FLORA 62: INPE 64: ago. <1993> 66: Sao Jose dos Campos 67: BR 68: PRP 90: b 76: VEGETACAO 87: FLORESTAS 82: 83: Foi testado um modelo de inventario florestal em multiplo estagio na Floresta Nacional do Tapajos, localizada proximo da cidade de Santarem, Estado do Para, Brasil.

The relationship between geology, relief, soils and vegetation cover is poorly investigated. This lack of knowledge is caused by many factors, such as the non-accessibility to the area, its environmental complexity, the absence of systematic and integrated multidisciplinary studies, etc. These problems can be partially solved by the use of Digital Processing Image (DPI)and Geographical Information System (GIS). In order to perform this research, digital magnetic images (derived from aerial profiles)were created. This geophysical data (N-S profiles)were converted to a regular grid of 30m and subsequently, to a black and white digital image with a Cubic Spline interpolation algorithm.

This paper proposes a preliminary methodology of urban life quality evaluation integrating conventional data and remote sensing data by a GIS and relational database. This methodology is based on a conceptual model envolving the following variables: salary of urban population (income), contagious disease occurrence (health), violent crimes occurrence (criminality)and environmental variables extracted from remote sensing products like vegetation density (green areas)and built space pattern (texture) MFN: 6186 91: FDB_19980319 92: FDB-MLR 30: Revista UNIVAP 31: 1 32: 1 40: Pt 41: Pt 41: En 42: 58: DSR 61: 64: set. <1993> 68: PRE 90: b 83: The objective of this research was to evaluate the influence's valuation of view geometry variation in spectral behavior of herbaceous vegetation and soil, underlying in composition pastures for Brachiaria decumbens Stapf. cv. Basilisk Stapf and Brachiaria brizantha Stapf. cv. Marandu. The methodology development involved the report analysis between the spectral reflectance and the biophysics parameters of herbaceous vegetation and soil. For this purpose radiometric and biophysics measurements were done for 25 vegetation samples andone soil sample, in experiment areas of 1000 m2, for each species. The multispectral bidirectional reflectance measurements (500 to 1100 nm)were obtained in the view zenith angles ( v)of 0 , 15 , 30 , 45 and 60 for three sectors of azimutal plain ( v=0 , 90 and 180 ), with the solar zenith angle variation controlled for an amplitude of the 10 ( s=45 to 55 ) and the solar azimutal variation compensated in the acquisition method. The following vegetation parameters were measured: fresh and dry biomass, fresh and dry green biomass, droughtry biomass and leaf and stems; water content of total, green and droughtry biomassa, Leaf Area Index (LAI)and percentage of canopy cover. The soil parameters available were color, roughness and chemistry composition. This research intent was the comprehension of physical mechanisms involved in the directional reflectance factor distribution of complete homogeneous vegetation canopies and its influences in the relation between spectral behavior and vegetation parameters. The general scattering behavior was coherent with the dinamics observed in the literature and wassupported by two principal phenomena: the "phase function" and "geometric effect 1". The major trends observed in the reflectance factor ocurred in the azimuth in the principal plane of the sun ( s=0 and 180 ), while the minor trends ocurred in the azimuth direction perpendicular to the principal plane of the sun ( s=90 ). For all view angles and spectral bands the minimum reflectance ocurred near nadir ( v=0 ) and increased with increasing view zenith angles for all azimuth directions. This trend is caused by the shading of flower canopy layers, by components in the upper layers and by viewing different proportions of the layer components as the view angle changes ("effect 1"). In some cases by an additional effect of "phase function", the reflectance minimum was shifted slightly off-nadir in the foward scattering direction ( s=0 ). This shift was maximized for ocurrence of reproductive structures in the top layers of cover, because this structure is vertical and opaque. The near infra-red band was less influenced by view geometry variation than in the spectral bands of visible, because in the near infra-red band the transmitance was nearly equal to the reflectance for most structural components of herbaceous vegetation, while in the visible the reflectance is major, consequentely the "effect 1" is maximized. The major information content about vegetation cover was obtained in the principal plane of the sun, in the backscattering direction ( =180 ), than showed better relationships to the vegetation parameters, because of the ocurrence of "hot spot". The vegetation parameters of prodution and water content showed the best correlations, because its parameters have more association to the near infra-red, that exbited the better performance than visible bands, more associated to LAI and fresh and dry biomass components. The "effect 1" was the dominant phenomenon with controlled the directional reflectance distributions observed, but had its effects alterated by the action of aditional phenomenon "phase function" 1: SID/SCD 2: 6526 3: INPE-6526-PRE/2565 4: SRE 5: S 6: as 7: [07] 10: Morelli, Ademir Fernando 10: Formaggio, Antonio Roberto 10: Epiphanio, Jose Carlos Neves 12: Influencia da geometria de visada na reflectancia espectral de duas gramineas forrageiras 14: 27-42 MFN: 6220 18: Anais 40: Pt 41: Pt 42: 53: Simposio Brasileiro d Computacao Grafica e Processamento de Imagens, 6 54: 19-22 out. <1993> 56: Recife 57: BR 58: DPI 59: PRIMA 61: 64: <1993> 68: PRE 90: b 83: A PC-based implementation of a Diffusion Limited Aggregation (DLA)Model is presented, with emphasys in the animation of the process.

Os radiometros modernos, de contrucao baseda em redes CCD e circuitos integrados, tem facilitado bastante essa atividade devido a sua portabilidade e rapidez de medicao; entretanto, o estudo das correlacoes entre os dados radiometricos de campo e aqueles obtidos atraves de imagens orbitais, exige que os sistemas de medicao possuam uma elevada taxa de amostragem e um campo de visada sque permita a medida de amostras com dimensoes compativeis com a resolucao das imagens. Com o objetivo de atender esse tipo de necesidade, o Laboratorio de Radiometria do INPE (LARAD), desenvolveu o SADA, um Sistema de Aquisicao de Dados Aerotransportado que utiliza um helicoptero como plataforma operacional. Este sistema, permite realizar a radiometria de objetos da superficie terrestre com a resolucao geometrica e taxa de amostragem mais adequadas a analise das propriedades espectrais de objetos extensos ou de dificil acesso como florestas e corpos d'agua. O primeiro teste operacional com o SADA, foi realizado no reservatorio de Barra Bonita (SP)e teve como objetivo a aquisicao de espectros de reflectancia dos diversos tipos de agua do reservatorio. Este experimento demontrou que o sistema possui excelentes caracterisiticas operacionais e devido a sua flexibilidade e rapidez de amostragem e bastante adequado para esse tipo de objetivo 91: FDB-19921209 92: FDB-MLR 101: D 109: 1 110: 1 110: 1 110: 3 110: 1 110: 1 110: 1 110: 1 110: 1 111: Arquivo 111: Aquisicao 111: Carlos A.

Examination of the data in intervals has brought out their value for the following synoptic scale evaluations: quantification of total deforestation and deforestation rates; forest recovery; biomass; estimation; water and energy balance; and detection of natural disturbances. Considering the uncertainties involving carbon fluxes from tropical forests, the role of GIS based remote sensing techniques is apparent for improving knowledge of past rates of deforestation, monitorings: future forest conversions and getting best sampling and extrapolating approaches for biomass estimations, espacially for secondary forest for which there are no data available currently. Models of forest change in response to human interference require a prior characterization of the bacground noise of natural change visible over just eight years of TM recording: Large forest fires associated with the 1982/83 El Nino; natural cj]hange in bamboo forest of Acre an SW Amazonas; mortality from anomalous flooding of terra firme forest; and large blowdowns (>30 hectares). Although naturally disturbed areas may offer a unique opporunity for remote sensing studies of "untouches" forest recover, their ecological impacts are far less important than the anthropogenic activities.

The model, named FORECOS uses Leaf Area Index as the main input variable. LAI is generally accepted as being the most important variable characterinz the exchange of energy mass in forest ecossystem. There is substantial work done showing that LAI can be estimated from remotely sensed data, on the basisof the correlation that exists between LAI and vegetation index, obtained by rations between spectral bands. Simulation and sensitivity analysis on some critical parameters were used to test the suitability of the model to represent the processes described by the model. By using digital classification procedures, patterns of vegetation were identified that should correspond to variations on LAI values although measurements could not be taken at this step. The results that come out from the classification suggest that LAI values are homogeneous in all test sites. Then the use of a unique regional value within the simulations is felt to be valid. The results showed that the model was able to represent the relative differences for both the hydrology and tha carbon cycles, for the three sites chosen. Validation with measurements of some state variables and independent variables related to net primary production and hydrology could not be done at this step either, and is to be poursued as this reserach go on 91: FDB-19930623 92: FDB-MDF 101: D MFN: 6568 1: SID/SCD 2: 7586 3: INPE-7586-PRE/3438 4: SRE 5: MC 6: am 7: [07] 10: Batista, Getulio Teixeira 10: Shimabukuro, Yosio Edemir 10: Lawrence, Wiliam T 12: Monitoramento da cobertura florestal atraves de indices de vegetacao do NOAA-AVHRR 14: 30-37 18: Anais 20: 7 21: v.2 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 87: MONITORAMENTO 87: INDICE DE VEGETACAO 87: COBERTURA VEGETAL 87: NDVI 87: NOAA-7 87: NOAA-9 87: NOAA-11 87: FLORESTAS 87: CLIMATOLOGIA 87: FLORESTAS 82: 83: This paper shows results of an experiment that explored the temporal variation of the vegetation index NDVI (Normalized Difference Vegetation Index)of several vegetation covers that occur in the Brazilian Legal Amazon. The value of NDVI obtained from NOAA satellite, has been shown for the estimation of a number of ecosystem variables, such as leaf area index and photosynthetic active absorbed radiation by the canopy, which in turn are essential for the modeling of gases, mass, and energy exchange between the biosphere and the atmosphere, contributing therefone, for the understanding of global change processes. Long-term monitoring (August 1981 to June 1991)of 8 vegetation types (Dense Forest ("Terra Firme" and "Varzeas"), Open Forest ("Terra Firme" and "Varzeas"), Transition Forest, Seasonal Forest ("Caatinga"), and two types of "Cerrado" which occur in the northern part of Brazil (3oN-18oS and 35oW e 74oW)is discussed. For each vegetation type, 10 samples of 3 x 3 pixels centered on the coordinates of selected samples were chosen and monthly composites of NDVI were obtained from GAC ("Global Area Coverage")data. Analyses also involved the yearly composite of NDVI to verify the inter-annual climatic variation. Throughout the analysis of 10 years of data it is clearly noticed the variation on the NDVI due to different satellites, indicating the need for calibration of AVHRR data for multitemporal studies. Seasonality of "Cerrado" and especially of "Caatinga" is outstanding, NDVI values vary from 3 to 4 times for the "Cerrado" and "Caatinga", respectively, in extreme years. Preserved "Cerrado" ("parque")was always distinct from Dense Forest ("Terra Firme")in any season of any year analyzed, however, better distinction is found during the dry season, especially in September. A comparison between normal and El Nino years indicated the influence of this phenomenon on the phenology of the forest vegetation. The phenology of forest covers, except "Caatinga" and "Cerrado" does not vary much throughout the years, however, for El Nino years, as 1983, there is a clear reduction in the NDVI values during the dry season, especially for the Transition Forest. This indicates the importance of multitemporal data for the characterization of forest ecosystems. Dense vegetation covers showed high NDVI values ( 0.5), "Caatinga" had an average NDVI of 0.35 with large seasonal variation, and "Cerrado" had average NDVI value 0.3 with great seasonal variation but never reaching the "Caatinga" greenness peak (NDVI 0.5) 91: FDB-19930623 92: FDB-MDF 101: D MFN: 6569 1: SID/SCD 2: 7588 3: INPE-7588-PRE/3440 4: SRE 5: MC 6: am 7: [07] 10: Faria, Kleber de 10: Krug, Thelma 10: Shimabukuro, Yosio Edemir 12: Aplicacao de tecnicas de geoprocessamento no monitoramento da cobertura florestal na area de influencia da ferrovia Carajas-Sao Luiz 14: 61-72 18: Anais 20: 12 21: v.2 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: ESTUDOS INTEGRADOS DO MEIO AMBIENTE 87: FLORESTAS 87: COBERTURA FLORESTAL 87: LANDSAT 3 87: LANDSAT 5 87: MONITORAMENTO 87: METODOLOGIA 87: FERROVIA 87: SIG 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: FLORESTAS 87: SISTEMAS MULTIESPECTRAIS DE VARREDURA 87: SATELITES LANDSAT 87: IMAGENS LANDSAT 82: 82: 83: The present study aims at proposing a methodology to evaluate the change in forest cover within the zone of influence of the railway of the railway Carajas-Sao Luis, using orbital images and Geographic Information System. the information about the ground cover was obtained through visual interpretation of LANDSAT MSS and TM images from 1980, 1985 and 1989.

The inventory of natural sites regarding types of soil rended as a base for the forest inventory, supplying stratified information, wich were then correlated with orbital data.

The examples given are derived from a digital dataset acquired over a sub-boreal forest in central Maine in 1990 by the NASA-JPL AVIRIS (Airbone Visible/Infrared Imaging Spectrometer). The forest area, in International Paper's Northern Forest, is comprised of mixed communities of hardwood and conifer tree species. The AVIRIS instrument gathers data from 400 to 2500 nm in 224 channels at bandwidths of approximately 10 nm. As a preview to the uses of hyperspectral data we have extracted several products from this dataset. They range from the traditional false color composite made from simulated Thematic Mapper bands and the well Known normalized difference vegetation index to much more exotic products such as fractions of vegetation, soil and shade based on linear spectral mixing models and estimates of the leaf water content at the landscape level derived using spectrum-matching techniques. Our research and that of many others indicates that the hyperspectral datasets carry much important information which is only beinning to be understood. This analysis gives an initial indication of the utility of hyperspectral data. Much work still remains to be done in algorithm development and in understanding the physics behind the complex information signal carried in the hyperspectral datasets. This work must be carried out to provide the fullest science support for high spectral resolution data to be acquired by many of the instruments to be launched as part of the Earth Observing System program in the mid-1990's 91: FDB-19930624 92: FDB-MDF 101: D MFN: 6573 1: SID/SCD 2: 7842 3: INPE-7842-PRE/3682 4: SRE 5: MC 6: am 7: [07] 10: Martins, Maria Lucia Ramalho 10: Sampaio, Maria Aparecida Bezerra 10: Almeida, Maria Aldemisa Gadelha de 10: Cruz, Maria Lucia Brito da 10: Costa, Raimunda Neuma Segundo da 10: Soares, Zilnice Maria Lebre 10: Medeiros, Jose Simeao de 10: Souza, Marcos Jose Nogueira de 12: Cobertura vegetal e antropismo no estado do Ceara: Uma abordagem utilizando imagens TM LANDSAT-5 14: 181-187 18: Anais 20: 7 21: 2 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: VEGETACAO 87: COBERTURA VEGETAL 87: LANDSAT 5 87: INTERPRETACAO VISUAL 87: SGI 87: MAPEADOR TEMATICO (LANDSAT) 87: IMAGENS LANDSAT 88: VEGETATION COVER 88: VISUAL INTERPRETATION 88: ENVIROMENTS 82: 83: The main objective of this work was the use of Remote Sensing techniques in order to identify the dimensions spatial and temporal anthropic action on the vegetal cover in Ceara State.

This paper presents a GIS-based methodology for calculating the incidence of deforestation among the different types of vegetation for the Amazon region.

Digital data in savanna area (woodland and shrub/grass savanna)were obtained from monthly NDVI image (Normalized Difference Vegetation Index)recorded in GAC format (Global Area Coverage). The annual integration of monthly composites shows a senoidal behaviour throught the year, with NDVI mean value of 0.39866 for woodland savanna and 0.32134 for shrub/grass savanna. Taking into account the seasonal variability of the vegetation, a maximum decrease around 32 83: in the NDVI values from wet to dry seasons was estimated. It could be concluded that the intra-annual variation of the photosynthetically active phytomass is influenced by the climatic conditions in the savanna environment 91: FDB-19930625 92: FDB-MDF 101: D 1: SID/SCD 2: 6579 3: INPE-6579-PRE/2616 4: SRE 5: MC 6: am 7: [07] 10: Santos, Joao Roberto dos 10: Shimabukuro, Yosio Edemir 12: O sensoriamento remoto como indicador das fenofases dos cerrados brasileiros: estudos de caso com dados AVHRR/NOAA 14: 249-257 MFN: 6576 18: Anais 21: v.2 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSR 58: SPG 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 87: FITOMASSA 87: FLORESTAS 87: LANDSAT-5 87: SPOT-1 87: RESPOSTA ESPECTRAL 87: IMPACTO AMBIENTAL 87: ESTIMATIVA 87: METODOLOGIA 87: INDICE DE VEGETACAO 82: 82: 82: 83: The Amazon forest has been the subject of much debate due to the extent of human intervention occurring there. The Brazilian Amazon, with 3.5 milion Km2, requires efficient systems of data collection for rational management of its forest resources. The present work develops a quantitative method for determining the biomass of tropical forest using satellite imagery from TM-LANDSAT 5 and HRV-SPOT in an area to be inundated for hydroeletricity. The study determined the correlation of biomass above-ground and tree measurements with spectral response and elevation in four samples: Dense Forest on Dry Land - Undulated Relief (samples 1 and 4), Dense Forest on Dry Land - Flat Relief (sample 2), and Floodplain Forest (sample 3). The forest samples were divided into three vertical levels for analysis. In comparison with the other forest levels, the spectral variables combined with the biomass variables did not permit the quantification of the biomass in the highest level of the forest. Regression analysis identifield the equations for quantifying biomass. The proposed method is practial and gave significant results using either image index or image fraction for both TM-LANDSAT or HRV-SPOT data. Of the twelve models tested, a linear model was which gave a significant relationship for the biomass in the intermediate and low levels with spectral and elevation variables. It is recommended that future studies determine the most efficient model to quantify the biomass in the three levels of the forest 91: FDB-19930625 92: FDB-MDF 101: D 1: SID/SCD 2: 6580 3: INPE-6580-PRE/2617 4: SRE 5: MC 6: am 7: [07] 10: Zerbini, Newton Jordao 10: Santos, Joao Roberto dos 12: Estimativa de fitomassa aerea em regiao de floresta tropical com uso de dados TM-LANDSAT 5 e HRV-SPOT 1 14: 275-280 MFN: 6577 1: SID/SCD 2: 7858 3: INPE-7858-PRE/3698 4: SRE 5: MC 6: am 7: [07] 10: Camara Neto, Gilberto 10: Souza, Ricardo Cartaxo Modesto de 10: Freitas, Ubirajara Moura 10: Paiva, Joao Argemiro de Carvalho 12: SPRING: Concepcao, Evolucao e Perspectivas 14: 308-317 18: Anais 20: 10 21: v.2 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DPI 61: 64: <1993> 68: PRE 90: b 76: GEOPROCESSAMENTO 87: SPRING 87: MODELOS DIGITAIS DE TERRENO 87: PROCESSAMENTO DE IMAGENS 83: This work describes the conception, evolution and perspectives for the SPRING system.

These problems can be partially solved by the use of Digital Processing Image (DPI)and Geographical Information System (GIS). In order to perform this research, digital magnetic imagfes (derived from aerial profiles)where criated. This geophysical data (N-SW profiles)were converted to a regular grid of 30mm and subsequently, to a black and white digital image with a Cubic Spline interpolation algorithm.

The study was developed based on interpretation technics obtained from spacial characteristics of remote sensig products derived products derived TM LANDSAT and SALR images and aeromagnetic data. Satructural lineament analysis and interpratation were direct toward the kinematic definition, general characteristics of shear belts as well as their structural/tectonic implications in the control of important know mineralizations of asbesthos and Cu, Pb and Zn massive sulfide deposits. Besides, propsitions of tectonics evolution of the area in study is presented as a contribution to the understanding of the regional geology. The same interpretations methodology which was taken as a regional basis, was tested on a pre-selected arae, where structura lineaments were integred with Cu, Pd and Zn geochmical images produced bey Geographical Information System (SIG). The results obtained in both regional and smei-detailed scales show that the already know minearalizations in the area are tectonically controlled by a fault system associated to a shear belt. Through the structural lineament analysis, together with geological data, four important deformational phases were recognized in the area, related to different sorts of stress, sometimes compreenssive, sometimes extensive, associated to transpession and transtetion systens. Knematics differs along the main structural lineaments, which were developed from the Archean to the Tertriary, during the tectonic evolution of the studyed area 91: FDB-21071993 92: FDB-FPS 101: D MFN: 6609 1: SID/SCD 2: 7904 3: INPE-7904-PRE/3739 4: SRE 5: MC 6: am 7: [07] 10: Veneziani, Paulo 10: Anjos, Celio Eustaquio dos 10: Nascimento, Flavia Maria de Fatima 10: Bignelli, Pedro Alberto 10: Dias, Ricardo Ribeiro 12: Reconhecimento de figuras de interferencia geradas pela superposicao de dobras flexurais na regiao do vale do Paraiba do Sul (SP)com a utilizacao de sensoriamento remoto 14: 368-375 18: Anais 20: 7 21: v.3 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSM 61: 64: <1993> 67: BR 68: PRE 90: b 76: GEOLOGIA 87: IMAGEM TM 87: LINEAMENTOS 87: LITOLOGIA 87: PROSPECSAO ESTRUTURAL 88: LENEAMENTS 88: LITHOLOGY 88: STRUCTURAL GEOLOGY 80: 83: The interpretation of remote sensing imagery carried out to search some circular structures obsreved on the region of Paraiba do Sul Valley, SP, Brazil. This region is set in the Sao Paulo Shear Belt which consists in a expressive transcurrent fault zone of the Southeast Folded Belt. In the studied area can be found tertriary sediments of Taubate Basin, sin-tardi-to post-tectonic migmatitic and gramitic rocks of Upper Pre- Cambrian age and also metasimentary rocks of Middle to Inferior Pre-Cambrian age. The Pre-Cambrian rocks were remobilized in Upper Pre-Cambrian thermal tectonic events. This remobilization is the principal evidence of policyclism and polimetamorphism of the studied region. The policyclic and polimetamorphormic evolution indicates that distensive as much as comrpenssive events caused deformations ranging from microscopic to regional scales. The remote sensing imagery registered some structural features representative ductile, ruptile-ductile, and ruptile deformetions that show the development of a process of single shear on the studied area, during Middle to Upper Pre-Cambrian age. At the end of Pre-Cambrian period the studied area qas submited to distensiv efforts responsible for the reactivation of ancient crustal lines of weaknees oriented according to NNW-SSE and ENE-WSW. This process had been continuous till Mesozoic to Cenozoic period and generated flexural folds with perpendicular axes, wich are recognizable on the remote sensing imagery as structural heihgs and lows. Theses structures resulted from the interference of two flexural folding patterns 91: FDB-04081993 92: FDB-FPS 101: D MFN: 6610 1: SID/SCD 2: 6601 3: INPE-6601-PRE/2638 4: SRE 5: MC 6: am 7: [07] 10: Kux, Hermann Johann Heinrich 10: Ahern, Frank J. 10: Raney, R.

Estas informacoes serao de extrema utilidade para o manejop do desenvolvimento, evitando-se assim graves problemas ambientais que anteriormente ocorreram nesta regiao. 91: FDB-04081993 92: FDB-FPS 101: D MFN: 6611 1: SID/SCD 2: 7907 3: INPE-7907-PRE/3743 4: SRE 5: MC 6: am 7: [07] 10: Horn, Ralf 10: Moreira, Joao 10: Muller, Hans-Jurgen 10: Witte,Franz 12: The DLR airborne experimental SAR system - E-SAR 14: 443-447 18: Anais 20: 4 21: v.3 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSM 61: 64: <1993> 67: BR 68: PRE 90: b 76: SENSORES E TECNICAS DE SENSORIAMENTO REMOTO 87: SAR 87: E-SAR 88: AIRBORNE EXPERIMENTAL 83: The DLR airbone experimental synthetic aperture radar (SAR)system E-SAR, designed and menufactured at the DLR institut uferochfrequenztechnik, is a research tool to elaborate SAR related problems concerning both system performance and data analysis.

Due to the success it has reached, this thecnology has expanded and today it is possible to find around 3000 users in Brasil. But even with great numbers of users, just few of then had the opportunity of having a deeper learning remote sensing. The qreat ,ajority got knowledge on remote sensing through short-tem training courses. The main reason for this is the lack of long-term courses like master and basically specialization courses. so, due to this, UNIVAP University in patnership with INPE decide to create specialization courses in remote sensing and geoprocessing applied to natural resources 91: FDB-1181993 92: FDB-FPS 101: D MFN: 6614 1: SID/SCD 2: 7910 3: INPE-7910-PRE/3746 4: SRE 5: MC 6: am 7: [07] 10: Sausen, Tania Maria 10: Silva, Jose Demisio Simoes da 10: Bertti, Gloria Cardozo 10: Carvalho, Roseli Monteiro de 12: Setor de treinamento do INPE, objetivos, politica e diretrizes 14: 20-25 18: Anais 20: 5 21: v.4 40: Pt 41: Pt 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio 1993 56: Curitiba 57: BR 58: DSM 61: 64: <1993> 67: BR 68: PRE 90: b 76: TRANSFERENCIA DE TECNOLOGIA 87: POLITICA 87: TREINAMENTO 87: DIRETRIZES 83: As atividade de treinamento do INPE vinham sendo realizados com maior ou menor sucesso, dependendo da dedicacao pessoal dos servidores nelas envolvidos, ou do apoio das chefias, apesar de nao haver uma politica de treinamento a nivel einstitucional.

This paper presents a preliminary analysis of this daset. The wide swath C-band HH polarizaed image has been enlarged to 1:100,000 in a photographic form for manual interpretation. This was compared with a vegetation map produced primarily from Landsat TM data and with single-band and colour composite images derived from a decomposition analysis of TM data. The SAR image shows well the topography and drainage network defining the differtent geomoorphological units, and canopy texture differences which appear to be related o the size and maturity of the forest canopy. Areas of recent clearing of the primary forest can also be identifield on the SAR image. The SAR system appears to be a source of information for monitoring tropical forest which is complementary to the Landsat Thematic mapper 91: fDB-19930816 92: FDB-MLR 101: D MFN: 6630 1: SID/SCD 2: 7906 3: INPE-7906-PRE/3742 4: SRE 5: MC 6: am 7: [07] 10: Bevilaqua, Rute Maria 12: Sensoriamento remoto de mar de gelo 14: 417-423 18: Anais 20: 6 21: v.3 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSM 61: 64: maio <1993> 68: PRE 90: b 76: SENSORES E TECNICAS DE SENSORIAMENTO REMOTO 87: GELO 87: MONITORAMENTO 87: ERS-1 87: SENSORES 87: BEPERS 82: 83: Este trabalho trata do estado da arte no sensoriamento remoto de gelo no mar.

Neste trabalho foram utilizados dados do sensor AVIRIS coletados em 30 de setembro de 1991 sobre o Mono Lake concomitantemente a aquisicao de amostras d'agua em 14 estacoes limonologicas. 91: FDB-19930818 92: FDB-MLR 101: D MFN: 6634 1: SID/SCD 2: 6671 3: INPE-6671-PRE/2702 4: SRE 5: MC 6: am 7: [07] 10: Pereira Neto, Osvaldo Coelho 10: Valerio Filho, Mario 12: Analise comparativa de metodos para elaboracao de cartas de declividade aplicadas a estudos do Meio fisico 14: 226-232 18: Anais 20: 7 21: v.4 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSM 61: 64: <1993> 68: PRE 90: b 76: ESTUDOS INTEGRADOS DO MEIO AMBIENTE 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: SGI 87: DECLIVIDADE 87: BACIAS HIDROGRAFICAS 87: SIG 88: STEEPNESS 88: HYDROLOGICAL BASINCARTAS DE DECLIVIDADE 82: 83: Integrated analysis of physical environment data as an aid to studies related to land classification techniques, urban planning, geotechny, and geo-envirnment need as information basis, a steepness chart. The present work has the objective of comparing three methods of steepness chert acquisition from the Ribeirao Cafezal hidrographic basin located among the municipalities of Londrina, Cambe and Rolandia in the state of Parana, Brazil. Two out of the theree methods utilised use a Geographical Information System developed by the National Institute of Sapace Research (INPE)staff, and the third one is based on analog abacus. In this paper, approaches inherent to the different methods are presented and discussed as well as the pratical aspects are taking into account to obtain the steepness charts are analysed. The results show that the steepness charts produced at a scale of 1:50.000 using the GIS methods present advantage in terms of time when compared with the abacus methods but with lower accuracy of the sharp borders of the steepness classes 91: FDB-19930823 92: FDB-MLR 101: D MFN: 6635 1: SID/SCD 2: 7919 3: INPE-7919-PRE/3755 4: SRE 5: MC 6: am 7: [07] 10: Santos, Athos Ribeiro dos 10: Crepani, Edison 12: Contribuicao do sensoriamento remoto aplicado a geologia no estudo do assoreamento do Rio Taquari, Pantanal Matogrossense 14: 261-266 18: Anais 20: 6 21: v.4 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSM 61: 64: <1993> 68: PRE 90: b 76: GEOLOGIA 87: SEDIMENTOS 87: ASSOREAMENTO 87: EROSAO 87: BACIAS HIDROGRAFICAS 87: GEOLOGIA ESTRUTURAL 87: MEIO AMBIENTE 87: LANDSAT-TM 87: DRENAGEM 88: SEDIMENTS 88: HIDROLOGICAL BASIN 88: EROSION 88: DRAINAGE 82: 82: PANTANAL (MT)> 82: BACIA DO RIO TAQUARI (MT)> 83: This work discusses the contribution of the Landsat TM imagery to the study of the accumulation of the sediments in the region of the Taquari River, in the southern part of Pantanal Matogrossense.

This buoy, tracked by NOAA satellites thought the ARGOS system, stayed at the sea in the period between 1/26/1989 and 2/21/1989. Using hydrographic data colected in situs by the Brazilian Oceanographic support ship, the Barao de Teffe, the horizontal distributions of temperature (T), salinity (S)and density of the sea water were obtained for the period of the experiment. By comparing the buoy's trajectory with the T,S and Density distributions, it was noted that variations int the flow patterns measured by the buoy were caused by the presence of two oceanic fronts in the study area. From the results of this experiment, it is shown that the Brazilian drifting buyos tracked by the ARGOS system are strong tools that can be used to detect and describe oceanic fronts on a sinoptic basis 91: FDB-19930823 92: FDB-MLR 101: D MFN: 6641 1: SID/SCD 2: 7922 3: INPE-7922-PRE/3758 4: SRE 5: MC 6: am 7: [07] 10: Stevenson, Merritt Raymond 10: Lorenzzetti, Joao Antonio 10: Stech, Jose Luiz 10: Arlino, Paulo R.A. 10: Costa, Vladimir M.da 12: SIMA: an integrated envirnmental monitoring system 14: 300-310 18: Anais 20: 11 21: v.4 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DCT 61: 64: <1993> 68: PRE 90: b 76: OCEANOGRAFIA 87: MONITORAMENTO 87: BOIAS OCEANOGRAFICA 87: SISTEMA ARGOS 87: MEIO AMBIENTE 87: SIMA 87: SATELITES NOAA 87: BOIAS DE DERIVA 87: IMAGENS NOAA 88: ARGOS SYSTEM 88: OCEANOGRAPHY 88: ENVIRONMENT 82: 83: During the past decade there has been a sharply increasing interst and need in obtaining environmental information related to the aquatic domain. The ability to receive serial information about current or recent weather hydrological or environmental (quality)conditions, in a timely and reliable fashion is now recognized as the basis for any modern environmental monitoring system, wather the data are used for the protection of the environment, or to minimize the negative impact of extreme environmental conditions on the day-to-day safety of communities. Because the reliability of receving such data via convectional telephone lines is often affected bythe same adverse weather or environmental conditions being reported by the system, a modern system based on telemetry via satellite, that is, a system where the environment is remotely sensed, should bde considered among the most reliable and desirable systems. This report presents the development of Project SIMA, an integrated system for monitoring the aquatic environment. Because SIMA is based on the ARGOS system aborded the polar orbiting NOAA satellites, SIMA has no global limits for its project is to design and develop a prototype system that can be used to monitor conditions in a coastal region where the possibility of oil spills exist, or in enland waters such as reservoirs and lakes, where the system can monitor changes in environmental parameters that may indicate the onset of floos, pollutants entering a reservoir, and so forth 91: FDB-19930823 92: FDB-MLR 101: D MFN: 6642 1: SID/SCD 2: 7926 3: INPE-7926-PRE/3762 4: SRE 5: MC 6: am 7: [07] 10: Sausen, Tania Maria 10: Nielsen, Christine 12: The development of sensing in Brazil and Canada: comparative case studies 14: 431-436 18: Anais 20: 6 21: v.4 40: Pt 41: En 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 58: DSM 61: 64: <1993> 68: PRE 90: b 76: TRANSFERENCIA DE TECNOLOGIA 87: SENSORIAMENTO REMOTO 87: PROGRAMAS 87: TREINAMENTO 87: MERCADO 88: REMOTE SENSING 88: PROGRAMS 83: The remote sensing programs of Brazil and Canada originated in late 1960s through participation in NASA's Landsat program. National governments of both countries have supported the development of remote sensing activities. Both countries have shared common interests in developing this technology in terms of large geographic areas and strong interests in natural resources exploration and management. Despite these similarities, the situation in the two countries are quite different today. There are between 3000 and 500 remote sensing users in Canada. The majority are in the private sector. While there are approximately 3000 remote sensing users in Brazil, 85 83: of the users are in the public sector. Just two companies are 100 83: involved. There are many sectors of the economy that could benefit from remote sensing information; however, this large market remains undeveloped. One may conclude that more needs to be done if remote sensing tecchnology is to be transferred sucssesfully from the public to the private sector in Brazil. The purpose of this research is to gain a better understanding of the evolution of remote sensing activities in Brazil and Canada over the past 25 years in order to further technology transfer/diffusion activities within the Brazilian context 91: FDB-19930814 92: FDM-MLR 101: D MFN: 6643 1: SID/SCD 2: 7912 3: INPE-7912-PRE/3748 4: SRE 5: MC 6: am 7: [07] 10: Mello, Eliana Maria Kalil 12: Experiencia brasileira no treinamento em planejamento e controle de projetos, integrante ao Curso Internacional de Especializacao em Sensoriamento Remoto ONU/INPE, Brazil 40: Pt 41: Pt 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 58: DSM 61: 64: <1993> 68: PRE 90: b 76: EDUCACAO 87: CURSOS 87: TREINAMENTO 87: HISTORICO 87: SENSORIAMENTO REMOTO 83: Este trabalho tem o objetivo de apresentar o historico, o programa e as perspectivas futuras do treinamento em planejamento e controle de projetos, integrante ao Curso Internacional de Especializacao em Sensoriamento Remoto, oferecido pelo Governo Brasileiro e organizado pelo Ministerio da Ciencia e Tecnologia-MCT do Brasil, Instituto Nacional de Pesquisas Espaciais e pela Organizacao das Nacoes Unidas-ONU.

Todavia, falta um planejamento adequado, principalmente dos recursos hidricos. O presente trabalho, desenvolvidos no LMRSPB, faz parte do "Projeto de Aproveitamento de Recursos Integrados do Rio Surucu". Com base nas imagens TM foi feito um levantamento do uso atual da terra, da drenagem e dos corpos d'agua, e uma analise temporal, usando-se as imagens de 1984 e de 1990. Como resultados foram definidas quatro grandes classes de uso da terra: Propriedades de Grande Porte ( > 300 ha ) com intensa atividade pecuaria (em algumas delas existe a agricultura irrigada); propriedades de medio Porte ( > 30 e < 300 ha ) 91: FDB-19930830 92: FDB-FPS 101: d MFN: 6651 1: SID/SCD 4: SRE 5: MC 6: am 7: [07] 10: Steffen, Carlos Alberto 12: Tecnicas radiometricas com o spectron SE-590 40: Pt 41: Pt 42: 52: Instituto Nacional de Pesquisas Espaciais 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 58: DSM 61: 64: <1993> 68: PRE 90: b 76: SENSORES E TECNICAS DE SENSORIAMENTO REMOTO 87: REFLECTANCIA ESPECTRAL 87: RADIOMETRIA 87: SPECTRON SE-590 87: SPECTRORRADIOMETRO 83: A medida de fator de reflectancia bidireciona espectral (FRBE)e importante para a compreensao dos fenomenos decorrentes da interacao da radiacao solar com os objetos da superficie terrestre.

Esta falta de conhecimento e causada por varios fatores, tais como, dificuldade de acesso a area, complexidade ambiental, ausencia de estudos multidisciplinares, etc. Estes problemas podem ser parcialmente resolvidos por meio do uso de dados de sensoriamento remoto e de geofisica. Neste contexto, o presente estudo foi baseado na extracao de informacoes geologicas, atraves da integracao digital de dados de sensoriamento remoto (TM-Landsat)e de geofisica (magnetometria), utilizando-se a transformacao IHS (intensity, hue e saturation). Para esta pesquisa foram utilizados os seguintes dados: imagens digitais de magnetometria (reducao ao polo e ao equador msgneticos, susceptibilidade magnetica, primeiro e segundo derivativos e continuacao para cima)a partir do campo magnetico total, derivadas de perfis aerotransportados; imagens TM-Landsat (6 bandas refletidas na faixa do visivel ao infra-vermelho); fotografias aereas; mapas geologicos e geobotanicos. Os dados geofisicos (perfis N-S)foram convertidos para grades regulares, com um espacamento de 30 metros e posteriormente, para imagens digitais com o auxilio de um algoritmo de interpolacao Cubic Spline. Estas imagens foram integradas com as imagens TM, no espaco IHS, com o objetivo de promover uma melhor visualizacao das correcoes existentes entre as informacoes. Um mapa fotogeologico foi confeccionado no contexto de subsidio aos resultados obtidos com a transformacao IHS e no aperfeicoamento de conhecimento geologico da area do pojuca. na transformacao IHS foram integradas a primeira componente principal das seis bandas utilizadas do TM (canal intensidade)e a imagem transformada de reducao ao equador (canal de hue). O produto final forneceu informacoes adicionais, principalmente, em relacao as feicoes texturais e topograficas (componente principal)"coloridas" pelos padroes magneticos da area.

The problem of filtering in an image is posed as an estimation problem. 1: SID/SCD 2: 5519 3: INPE-5519-PRE/1794 4: SRE 5: MC 6: am 7: [07] 10: Frery, Alejandro Cesar Orgambide 10: Sant'Anna, Sidnei Joao Siqueira 12: Non-adaptive robust filters for speckle noise reduction 14: 165-174 MFN: 6684 1: SID/SCD 2: 7908 3: INPE-7908-PRE/3744 4: SRE 5: MC 6: am 7: [07] 10: Kuplich, Tatiana Mora 10: Soares, Joao Vianei 12: Analise preliminar de avaliacao de uso da terra com base em imagens orbitais de um radar e de um sensor otico (ERS-1/SAR e Landsat/TM) 14: 448-455 18: Anais 20: 8 21: v.3 40: Pt 41: Pt 42: 52: INPE 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 83: Este trabalho apresenta os resultados preliminares de uma an lise comparativa entre produtos de dois sensores de natureza distinta para avaliacao de classes de uso da terra: o Radar de Abertura Sint‚tica dos Sat‚lite Europeu de Sensoriamento Remoto (SAR/ERS-a e o mapeador tem tico do £ltimo sat‚lite americano da s‚rie Landasat (TM/Landasat-5).A  rea teste ‚ de 400 Km2 e localiza-se na porcao noroeste do munic¡pio de Campinas, SP.

The study area was the Guanabara Bay, in Rio de Janeiro, Brazil. Water samples were collected on two dates, coincident with Landsat passages, and when different tide conditions were present at the Bay. TM Bands 1, 2, 3, 4, and 6, band ratios 1/3 and 2/3 and principal component analysis of TM Bands 1-4 were compared with in situ measurements and laboratory analysis of water samples. Some water quality parameters were very well correlated with the digital remotely sensed data, especially during high tide: for instace, iron and manganese concentration in total suspended solids; salinity and Secchi depth; temperature and Secchi depth; temperature and total suspended solids; total suspended solids and Bands 4 and 6; Secchi depth and Bands 4 and 6; temperature and Band 6. Lower correlation coefficients, although also significant, were found for the low tide condition. No correlation was found with chlorophyll-a quate to analyze temperature, Secchi depth, total suspended solids, and iron and manganese contents in the total suspended solids for the polluted estuary area studied. 91: FDB-19940613 92: FDB-MLR 101: D MFN: 6717 1: SID/SCD 2: 7358 3: INPE-7358-RPQ/710 4: SRE 5: MP 6: m 7: [07] 17: Fundacao SOS MAta Atlantica 17: Instituto Nacional de Pesquisas Espaciais 18: Evolucao dos remanescentes florestais e ecossistemas associados do dominio da Mata Atlantica no periodo 1985-1990 20: 47 38: Atlas da evolucao dos remanescentes florestais e ecossistemas associados do domin¡nio da Mata Atlantica no periodo 1985-1990 40: Pt 41: Pt 42: 58: GRI 62: INPE 64: <1993> 66: Sao Jose dos Campos 67: BR 68: RPQ 90: b 76: ESTUDOS INTEGRADOS DO MEIO AMBIENTE 87: MAPEAMENTO 87: FLORESTAS 87: RESTINGAS 87: MANGUEZAIS 82: 91: FDB-19940613 92: FDB-MLR 101: D MFN: 6732 1: SID/SCD 2: 5559 3: INPE-5559-PRE/1798 4: SRE 5: MC 6: am 7: [07] 10: Yanasse, Corina da Costa Freitas 10: Frery, Alejandro Cesar Orgambide 10: Sant'Anna, Sidnei Joao Siqueira 10: Hernandez Filho, Pedro 10: Dutra, Luciano Vieira 12: Statistical analysis of SAREX data over Tapajos - Brazil 14: 25-40 18: Workshop procedings 38: (ESA wpp-76) 40: En 41: En 42: 52: ESA 53: South American Radar Experiment - SAREX-92 54: 06-08 Dec. <1993> 56: Paris 57: FR 58: DPI 58: DSR 61: 64: <1993> 68: PRE 90: b 76: VEGETACAO 87: FLORESTAS 83: SAREX data over Tapajos region are studies through the use of goodness of fit tests and of the spatial autocorrelation function, in order to discriminate land use.

A closed (recursive)computational form is provided for the K cumulative distribuitom function, as well as the estimators derived from the substitution method. The sensitivity of the cumulative distribuition function with respect to possible discretizations od the parameters due to limitations imposed by recursive form is discussed. The recursive form form of the cumulative distribution function of K multilook random variables is used to perform the KolmogorovSmirnov (KS)test of goodness of fit over SAREX data. It is shown that, mainly for forest fata, the fit with the K multilook distribution is superior to some of other distributions that frequently appear in the literature.

Estes dados sao de grande importancia ao planejamento regional e local. Em paises em que ha pouca disponibilidade de documentacao cartografica precisa e atualizada em funcao de restricoes economicas os dados obtidos de imagens de satelite parcialmente podem preencher a ausencia de dados usando tecnicas de sensoriamento remoto (multisensor/multitemporal)e de integracao de dados (GIS).

Tais instrumentos orientam na selecao de areas propiciais a expansao urbana, as atividades industriais e agrossilvopastoris. Elas tambem contribuem para evitar e solucionar problemas ambientais relacionados com essas atividades, com a exploracao de minerios, com os recursos hidricos e riscos geologicos, como movimentos de massa, vulcanismo e inundacoes. A medida que aumenta a resolucao (espacial, espectral e temporal)e novos recursos tecnologicos, como a visao esteroscopica, tornam-se disponiveis, imagens orbitais obtidas por sensores como o TM e o HRV, respectivamente dos satelites LANDSAT e SPOT, constituem-se em instrumentos poderosos para estudos geomorfologicos. Entretanto, apesar desses avancos terem aumentado a aplicacao de imagens de satelites para mapeamentos geomorfologicos, principalmente em pequenas escalas, o potencial real desses dados ainda nao e suficientemente conhecido e explorado. Neste sentido, o objetivo deste trabalho e avaliar a contribuicao efetiva das imagens TM para a cartografia geomorfologica e determinar o nivel de informacao geomorfologica que pode ser obtido atraves da analise e interpretacao destas imagens. Para alcancar este objetivo foram analisadas imagens TM das bandas 1, 2, 3, 4, 5 e 7,individualmente, alem de composicoes coloridas, em diferentes formatos, escalas e de cinco datas distintas, referentes a duas areas-teste, uma localizada no municipio de Sao Jose dos Campos e outra no municipio de Caraguatatuba, no Estado de Sao Paulo, regiao sudeste do Brasil.

Nesta epoca foram enviados 14 pesquisadores do INPE para os Estados Unidos, com a finalidade de serem treinados. Ao voltarem ao Brasil, este grupo de pesquisadores iniciou dois programas basicos de sensoriamento remoto: o projeto RADAM,naAmazonia, e o projeto SERE no INPE. Logo o INPE percebeu que seria necessario criar um programa para suprir a falta de pessoal qualificado nesta nova tecnologia. Assim, para preencher esta lacuna foi criado no INPE, em 1972 o programa de mestrado em sensoriamento remoto. Ate 1978 este programa era dedicado exclusivamente aos pesquisadores do INPE. A partir deste ano, como a maioria dos pesquisadores deste Instituto ja estavam com o seu mestrado concluido, o programa passou areceber candidatos de outras instituicoes brasileiras. Assim desde o comeco em 1972, ao redor de 100 pesquisadores ja obtiveram seu titulo de mestre pelo INPE, sendo que deste total, 32 sao pesquisadores do Instituto. A quase totalidade destes mestres continua trabalhando com sensoriamento remoto. Muitos ja desenvolveram ou estao desenvolvendo programas de doutorado relacionado a sensoriamento remoto. A partir do ano de 1993, o programa de mestrado passou a oferecer vagas para candidatos oriundos de paises latino-americanos, assim este ano temos 2 alunosargentinos, 1 colombiano e 1 venezuelano. O objetivo deste trabalho e tracar um perfil da atuacao destes profissionais, formados pelo programa de mestrado do INPE, no mercado de sensoriamento remoto no pais. Informacoes como area de atuacao, quando conclui o mestrado, tema da tese, se continua trabalhando em sensoriamento remoto, em que tipo de instituicao trabalha,etc., foram levantadas atraves de questionarios.

A determinacao de tais areas usualmente tem sido feita com base na analise dos elementos componentes do meio fisico (de naturaleza geomorfologica, geologica, vegetacional,etc.)elementos esses que sao analisados diferenciadamente em funcao de peculiaridades da metodologia utilizada na compartimentacao. A analise diferenciada dos elementos fisiograficos pode trazer como consequencia a ocorrencia, para uma mesma area, de diferentes compartimentacoes, o que constitui um fator limitante para estudos multi e interdisciplinares sobre uma dada regiao.

No presente trabalho, avalia-se o desempenho de tres dos mais conhecidos modelos, que sao o SUITS, o SAIL e o SRVC, alem de se propor um modelo simplificado (o MSCR)para o calculo da reflectancia. Foi montado um experimento com a cultura da soja (Glycine Max (L.)Merril - variedade IAC-5), onde foram coletados dados de dois tipos: (a)biofisicos: altura das plantas, area foliar, porcentagem de cobertura verde sobre o solo e distribuicao angular de folhas; e (b)radiometricos: reflectancia do solo, radiacao difusa incidente, reflectancia do dossel. Alem disso, outros parametros foram obtidos em escritorio e em laboratorio, tais como: numero total de classes constituintes do dossel, reflectancia e transmitancia hemisfericas dos elementos do dossel, proporcao de folhas em diferentes intervalos de inclinacao, indice de area foliar, area de folhas por plano de projecao, coeficiente de extincao por plano de projecao, declinacao solar, angulo zenital de iluminacao, angulo azimutal de iluminacao, reflectancia nas bandas do TM. A partir dos varios dados e resultados obtidos, conclui-se que o modelo SUITS apresenta o melhor desempenho, seguido pelo SAIL. Em termos de um fator de correcao para os modelos, verifica-se que os modelos SRVC e MSCR apresentam uma melhor resposta, quando comparados aos modelos SUITS e SAIL. Com relacao ao modelo proposto, verifica-se que ele apresenta um desempenho satisfatorio, quando comparado aos modelos SUITS, SAIL e SRVC 91: FDB-19950123 92: FDB 101: D MFN: 6761 1: SID/SCD 2: 5530 3: INPE-5530-PRE/1797 4: SRE 5: MC 6: am 7: [07] 10: Kurkdjian, Maria de Lourdes Neves de Oliveira 12: Aplicacoes de sensoriamento remoto ao planejamento urbano 14: 103 18: Resumos 40: Pt 41: Pt 41: En 42: 52: SELPER 53: Simposio Latinoamericano em Percepcion Remota, 6 54: 03-08 oct. <1993> 56: Cartagena 57: CO 58: DSM 61: 64: <1993> 68: PRE 90: b 76: PLANEJAMENTO TERRITORIAL 87: PLANEJAMENTO URBANO 87: FOTOGRAFIA AEREA 87: IMAGENS 88: URBAN PLANNING 88: AERIAL PHOTOGRAPHY 88: IMAGERY 83: O processo de planejamento urbano como um processo de tomada de decisao voltado a consecucao de um cenario futuro desejado requer, para sustenta-lo, um eficiente sistema de informacoes espacializadas.

The model, named FORECOS, uses Leaf Area index, LAI, as the main input variable representing the vegetation. LAI is generally accepted as being the most important variable characterizing the exchange of energy and mass between forest ecoysstems and the atmosphere. There is substantial work done showing that LAI can be estimated from remotely sensed data, on the bases of the correlation that exists between LAI and vegetation index, obtained by rationing between spectral bands of optical sensors such as the Thematic Mapper (LANDSAT-TM)and the NOAA-AVHRR. Simulation and sensitivity analysis on some critical parameters were used do teste the suitability of the model to represent the processes of mass and energy transfer described by the model. By using digitalclassification procedures, patterns of vegetation were identified that should correspond to variations on LAI values, although "in situ" measurements could not be taken at this step. The results that come out from the classification suggestthat within the simulation is felt to be valid. The results showed that the model was able to represent the relative differences for both the hydrologic and thecarbon cycles, for the three sites chosen. Validation with measurements of some state variables and independent variables related to net primary production and hydrology could not be done at this step either, and is to be pursued as this research goes on 91: FDB-19950123 92: FDB 101: D MFN: 6766 1: SID/SCD 2: 7620 3: INPE-7620-PRE/3470 4: SRE 5: MC 6: am 7: [07] 10: Martini, Paulo Roberto 12: Panamazonian project to monitor South America tropical forest 14: 51 18: Resumos 40: En 41: En 42: 52: SELPER 53: Simposio Latinoamericano em Percepcion Remota, 6 54: 03-08 oct. <1993> 56: Cartagena 57: CO 58: DSM 61: 64: <1993> 68: PRE 90: b 76: FLORESTAS 83: PANAMAZONIA project is a joint effort of South America countries facing the monitoring of the Amazon Forest through the use of remotely sensed data and wall-to-wall procedure in computerized data set.Forest clear-cutting in Brazil have been evaluated since 1989 by means of GIS and LANDSAT frames. The methodology used to monitor deforestation and to measure the rates of deforestation from year-to-year in Brazil is now being transferred through Panamazoniaproject to others South American countries as: French Guyana, Suriname, Guyana, Venezuela, Colombia, Ecuador, Peru and Bolivia. The project was designed back inmay 1991 and three main topics were then established: i)Training of a technicalteam to develop the Project within each Panamazonia country; ii)Selection, acquisition and generation of color infrared LANDSAT prints at 250.000 scale of two periods (1984-1987)and (1988-1991); iii)Transference of GIS technology and implementation of a computerized data base in those countries where thes procedureswere nor available.

The value of NDVI obtained from NOAA satellites, has veem shown for the estimation of a number of ecosystem variables, such as leaf area index and photosynthetic active absorbed radiation by the canopy, which in turn are essential for modeling of gases, mass, and energy exchange between the biosphere and the atmosphere, contributing therefore, for the understanding fo global change processes. The phenology of natural vegetation under diversi climatic conditions due not only to seasonal variation but also episodic events sych ENSO (El Nino Southern Oscillation)is important for the understanting of these processes. Long-term monitoring (August 1981 to June 1991)of 8 vegetation types (Dense Forest "Submontana" and "Terras Baixas"), open Forest ("Submontana"and "Terras Baixas"), transition Forest, Seasonal Forest ("Caatinga"), and tow types of "Cerrado" which occur in the northern part of Brazil (3 N-19S and 35W and 74W)is discussed. For each vegetation type, 10 samples of 3x3 pixels were selected and monthly composites of NDVI were obtained from GAC ("Global Area Coverage")data. Yearly composites of NDVI were obtained ro verify the inter-annual climatic variation due to ElNino occurence. Throughout the analysis of 10 years of data is was clearly noteced the variation on the NDVI due to differene satellites, indicating the need for calibration of AVHRR data for multitemporal studies. Therefore, a calibration procedure proposed by NASA Goddard Space Flight Center and the University of Maryland (Los, 1993)were applied to the data to make possible quantitative comparisons of NDVI values obtained at different times. Seasonality of "Cerrado" and especially of "Caatinga" , is outstanding NDVI values vary from 3 to 4 times for the "Cerrado" and "Caatinga" respectively, in extreme years. Preserved "Cerrado"("parque")was always distinct from Dense Forest ("Terra Firme")in any season ofany year analyzed, however, better distinction is found during the dry season, especially in September. A comparison between normal an El Nino years indicated the influence of this phenomenon on the phenology of the forest vegetation. The phenology of forest cover, except "Caatinga" and "Cerrado" does not vary much throughout the year, however, for El Nino years, as 1983, there is a clear reduction in the NDVI values during the dry season, especially for the Transition ForestThis indicates the importance of multitemporal data for the characterization of forest ecosystems. Dense vegetation covers showed high NDVI values (-0,5), "Caatinga"had an average NDVI value -0,3 with large seasonal variation, and "Cerrado"had average NDVI value -0,3 with great seasonal variation but never reaching the"Caatinga" greeness peak (NDVI-0,5) 91: FDB-19950123 92: FDB 101: D MFN: 6768 1: SID/SCD 4: SRE 5: MC 6: am 7: [07] 10: Paradella, Waldir Renato 10: Singhroy V. 10: Veneziani Paulo 10: Liu Chan Chiang 10: Santos, Athos Ribeiro dos 10: Bignelli Pedro A 10: Dias, Ricardo R 12: South American Radas Experiment (Sarex-92)in the Carajas Mineral Province (Brazilian Amazon Region):data acquisiton and preliminary results 14: 163 18: Resumos 40: En 41: En 42: 52: SELPER 53: Simposio Latinoamericano em Percepcion Remota, 6 54: 03-08 oct. <1993> 56: Cartagena 57: CO 58: DSM 61: 64: <1993> 68: PRE 90: b 76: GEOLOGIA 87: SAREX-92 87: SAR 82: 82: 83: The SAREX 1992 campaign based on C-HH and C-VV data was undertaken during April 91 in Carajas (Pojuca), Brazilian Amazon region. The main objective of the project in this teste site is to teste the capability fo the SAR airbone data in various configurations (polarizations and incidence angles)to differentiate between litho-stratigraphic units and distinct types of tropical rain forest vegetation. An evaluation of RADARSAT (Nadir C-HH and wide-Swath-C-HH)and ERS-1 (Nadir C-VV)simulations will also be carried out. An area of 250 by 346 square km, from Tucurui reservoir up to the Carajas mountain range was covered by 5 wide swath mode flights parallel to ascending/descending ERS-1 orbits and covering an area of 3000 square Km were also collected. Finally, a Narrow Swath mode flight parallel to the main geological structures in the area (N70W)and corresponding to 1.152 square km was collected. All this data set was corrected for geometric distortions and antenna pattern effects. A digital mosaic based on the Wide Wath data was produced at CCRS and will support the regional photogeological interpretation (1:250.000)scale. The nadir and Narrow Swath mode data will be enhanced taking into account spatial and spectral attributes aiming at geobotanical classes and discriminations, lithological and structures mapping on detailed scale (1:50.000). Based on the preliminary analysis of the products available, the following conclusions are possible: 1- C-VV os better than C-HH aiming at the detection of phenological changes within the deforested section of therain forest; 2- C-HH os better than C-VV in the detection of minig activities mainly cut horizontal bench strip mines; 3- Faults, joints and geological lineaments seem to be well detectable in both polarizations; 4- "Campos Rupestres"(grassland)and ferruginous laterite duricrusts, both related to iron deposits have presented a remarkable and distinct backscattering response in both polarizations 91: FDB-19950123 92: FDB 101: D MFN: 6769 18: Resumos expandidos 19: 5 20: v.2 40: En 41: En 42: 53: Congresso Internacional da Sociedade Brasileira de Geofisica, 3 54: 07-11 nov. <1993> 56: Rio de Janeiro 57: RJ 58: DSM 61: 64: <1993> 68: PRE 90: b 76: GEOLOGIA 83: Bidirecional reflectance factor determinations in the visible and near-infrared (VNIR)of samples collected at the surface of the alkaline-ultramafic complex fo Maicuru (PA)were evaluated for iron and titanium content. The measured reflectance spectra present ubiquitous absorption features characteristic of ferric oxide: broad 920 nm and 400-500 nm lows and a 650 nm shoulder. These spectral characteristic are indicative of the predominance fo goethite as the source of ferric oxide. On the other hand, the presence of titanium is inferred from the overall spectral behaviour. In general, as the titanium oxide content in our sam0ples increases in relation to iron, the measured spectra tend to show lower albedo (overall reflectance from 400 to 2500 nm). The ratio fo correlation (linear correlation)of 0.64)with the reflectance ratio 1500/920nm:low titanium content samples have high reflectance ratio values and vice versa. In fact, there is a strong exponential decrease of the form y = 8 and -1.7x when Ti/Fe contents are plotted aginst the 1500/920 nm ratios. In analogy to a carbon/iron oxide misture that presents similar exponential decay, we conclude that the titanium is associated to the presence of a component that behaves as an opague inVNIR. The titanium occurs as anatase and ilmenite, which is an opague. Another opague probably present is magnetite. As a proctical result, a band radiometer using bands centered at 1500 and 920 nm could possibly identify the titanium mineralized areas in the field 1: SID/SCD 2: 6624 3: INPE-6624-PRE/2661 4: SRE 5: MC 6: am 7: [07] 10: Vitorello, Icaro 10: Galvao, Lenio 10: Paradella, W.R. 12: Diferenciacao espectrorradiometrica de lateritas mineralizdas do Complexo de Maicuru(PA) 14: 988-992 MFN: 6770 1: SID/SCD 4: SRE 5: MC 6: am 7: [07] 10: Paradella, Waldir Renato 10: Vitorelli, Icaro 10: Galvao, Lenio S 12: Discriminacao de lateritas mineralizadas em fosfato e titanio no Complexo alcalino-ultramafico-carbonatitico de Maicuru (PA)atraves de tecnicas de sensoriamento remoto 14: 998-1002 18: Resumos Expandidos 20: 4 21: v.2 40: En 41: En 42: 53: Congresso Internacional da Sociedade Brasileira de Geofisica, 3 54: 07-11 nov. <1993> 56: Rio de Janeiro 57: BR 58: DSM 61: 64: <1993> 68: PRE 90: b 76: GEOLOGIA 87: FOSTATO 87: TITANIO 82: 83: Mineralized laterites developed over the Maicuru alkaline-ultramafic-carbonatite complex are distinguished in enhanced remote sensing orbital products.

Results indicate that the spectra from greisens are distinguished from the others by considering the slopes in the red-blue portion, and in the near-infrared beyond the 2300 nm wavelengths. The former are related to the presence of a greater amount of iron oxides in soils derived from biotite granites, especially the lateritic soils. The latter are due to hydroxyl minerals present in the hydrothermally altered materials. These results are useful in the selection of processing techniques of orbital imagery to enhance hydrohtermally altered areas.

Ground covers weredivided into four themes: natural forests, "capoeiras ",pastures in general and fire scars. Single-cell and maximum likelihood classification algorithms were used in the analysis. TM channel 4 was the best to identify fire scars, with digital counts differences in relation to other themes about two times higher than inother channels. Fire scars were also detected in channel 5, with the limitation thatr recent scars could be, mistaken with water. Channels 3 and 7 also contained information abour the scars. Results indicated that TM images can be used in automatic detection and assessment of biomass burning in tropical forests, contributing to the understanding of biogeochemical cycles related to the use of fire in thse areas. Comparison of the results for channels 3, 4 and 5 in two more TM scenes in 1987 and 1989, showed that minor variations accurred in the spectral definition of the themes, mainly as a result of atmospheric pollution from biomass burning MFN: 6855 1: SID/SCD 2: 5580 3: INPE-5580-TDI/543 4: SRE 5: T 6: m 7: [07] 16: Mantovani, Angelica Carvalho Di Maio 18: Deteccao de desmatamentos na floresta amazonica atraves de imagens AVHRR/NOAA e do sistema de informacoes geograficas SGI: metodologia e teste de um sistema potencial de alerta 19: Detection of deforestation in the Amazon forest using NOAA/AVHRR images and the geographic information system SGI: methodology and test of a potential alarm system 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Alberto Waingort Setzer (orientador); Flavio Jorge Ponzoni; Getulio Teixeira Batista; Thelma Krug; Evaristo Eduardo de Miranda 58: SPG 59: SER 64: dez. <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 73: 1989, 1990 76: ESTUDOS INTEGRADOS DO MEIO AMBIENTE 87: DESMATAMENTO 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: SGI 87: CLASSIFICACAO DE IMAGENS 87: FLORESTAS 87: AVHRR 87: SATELITES NOAA 87: SIG 87: RADIOMETRO AVANCADO DE RESOLUCAO MUITO ALTA 87: METODOLOGIA 87: DESFLORESTAMENTO 87: RADIOMETRO AVANCADO DE RESOLUCAO MUITO ALTA 87: MAPEADOR TEMATICO (LANDSAT) 87: IMAGENS LANDSAT 88: CHANGE DETECTION 88: DEFORESTATION 88: GEOGRAPHIC INFORMATION SYSTEMS 88: IMAGE CLASSIFICATION 88: INFRARED IMAGERY 88: RAIN FOREST 88: WARNING SYSTEMS 88: ADVANCED VERY HIGH RESOLUTION RADIOMETER 88: VEGETATION 82: 83: A rapida transformacao na cobertura florestal da Amazonia vem despertando preocupacao mundial em relacao ao impacto causado ao meio ambiente. Este trabalho descreve resultados obtidos no desenvolvimento de uma metodologia de baixo custo para um sistema de deteccao de novos desmatamentos na floresta tropical Amazonica. Este sistema combina imagens classificadas do sensor "Advanced Very High Resolution Radiometer"(NOAA/AVHRR)e um Sistema de Informacoes Geograficas (SIG/INPE). Imagens AVHRR, banda 3 (3,5um a 3,9um)de diferentes datas, corrigidas geometricamente, com resolucao de 1,1 km, foram comparadas automaticamente em formato digital.

The country has old and popular established traditions of burning the vegetation whenever possible, weak environmental concerns, and little or nor capability of fire detection in most of its territory (8 million km2). Among its main uses, fire is normally employed to renew pastures all over the country, to clear felled trees and shrubs in areas of new deforestation, and in sugar cane plantations prior to manual harvesting. A pronounced dry season of about four months in the southern and central regions during the austral winter create very favorable conditions for the wide spread use and propagation of fires.

The proposal of the research have been implemented in a Geographical Information System - SGI/INPE. The case study area is part of Chapada do Araripe-CE, within WRS 216.65C orbit of the american satellite LANDSAT-5. The area is located at the southern region of the Ceara State, involving the municipalities of Barbalha, Jardim, Missao Velha, Porteiras, Brejo Santo e Abaiara. The vegetation canopy land units and also the antropic actions, were identified by using aerial photographs of 1987, scale 1:32500, while the 1990 informations were extracted by visual interpretation of TM Landsat 5, TM 5 band processed in paper, black and white, scale 1:100000. Thematic databases were built (PIs)- vegetation canopy (1987 e 1990), altimetry, administrative boundaries, and infrastructure (roads)- all the data were digitalized, polygonizes and transformed from vector into raster. Then, the data integration tasks were done by using the function SOBREPOR, in order to quantify the areas of vegetation canopy which have been modified. To better visualize the antropic action, a 3-D model was generated. Finally, a thematic map was prepared on the scale of 1:100000 MFN: 6880 1: SID/SCD 2: 7905 3: INPE-7905-PRE/3740 4: SRE 5: MC 6: am 7: [07] 10: Veneziani, Paulo 10: Anjos, Celio Eustaquio dos 12: Prospeccao de agua termomineral na Regiao de Termas da Guarda (SC)com a utilizacao de tecnicas de sensoriamento remoto 14: 376-384 18: Anais 20: 9 27: v.3 40: En 41: En 42: 53: Simposio Brasileiro de Sensoriamento Remoto, 7 54: 10-14 maio <1993> 56: Curitiba 57: BR 58: DSM 61: 64: <1993> 68: PRE 90: b 76: GEOLOGIA 87: POCOS 87: AGUA TERMAL 87: LITOLOGIA 87: RADIOMETRIA 87: GEOMORFOLOGIA 82: 82: 83: This work aimed to localize bore hole points to exploit thermomineral groundwater in the Thermas da Guarda Region Santa Catarina State, Brazil. The geomorphological characteristics of the area consist: mountain relief with deep slope and "v" valleys. On the other hand lowlands filled with alluvium and colluvium sediments are essentially found where the principal fracturing directions are crossing themselves. The studied area is lithologically characterized by the ocourrance of coarse grained granitic rock and silex tectonic brecia. The main structural features are fractures (joints and faults). Lithological (tectonic brescia)and structural factors perform the control of the thermomineral water springs. Four maps were elaborated: 1- joint zone density and structural lineaments (faults)interpreted from TM Landsat imagery; 2- joint zone frequency using outcrop measures; 3- isovalues radiometric temperatures (PRT-5)and 4- topographic map.

The main obnective of the investigation in this area id to test the capability of airbone SAR data in various configurations (polarization incidence and azimuth angles)to differsntiate lithostratigraphic units, geological structures, distinct classes of tropical rain forest vegetation aiming at geobotonical application and mining activities. The SAR data were acquired under three different conditions. Wide swath mode was used to cover regionally the whole Province. Nadir and Narrow modes were used over the main mineralized areas. Based on the preliminary analysis of the Nadir and Narrow swath products,, the following conclusions are possible: (a)faults, joints and geological lineaments are well detectable in both polarizations, in a more detailed levels than the ones pubished on previous maps. However, forv the Narrow and Nadir modes, the radar backscatter is sensitive to look direction and local incidence angle. In low relief areas,perpendicular look direction is more important for the enhancement of subtle geological structures created extensive shadows, so the (b)lithostratigraphic units were also well detectable in accorfance to published on the maps. However ,unknown sub-divisions werealso identified and will be checked in the field;(c)C-HH data are slightly better than C-VV in the detection and characterization of mining activities, mainly cut horizontal bench od strip mines; (d)campos rupestres specific typesavanna vegetation associated with laterite (duricrusts)in iron-deposits, has presented characteristic SAR responses in both polarizations but more tonal variation are related to VV rather than to HH (Nadir and Narrow modes).

The reservoir was formed by damming the Tocantins river and flooded an area od approcimately 2430 Km2of forest land. Deforestation, forest burning and soil erosion is producing outstanding changes in the reservoir boundaries over the time. Attempts to use TM/Landasat to monitor aquatic weed infestation and changes in the water land boundary were limited to the dry season because of the heavy cloud cover from September thorough May. Radar data present an unique opportunity to obtain sensonal information on the reservoir boundaries and on the plant communities. During the experiment the Convair 580 SAR system acquired C band data at different modes (Nadir, Narrow and Wide modes)and polarizations (HH, VV< HV< and VH)Aerial color photographs at the 1:10 000 scale, TM/Landsat images and ERS-1 data were also acquird. In this paper the`empahasis is put on the differences between two parallel polarizations HH and VV obtained to simulate Radarsat and ERS-1 data respectively. To perform this asssesment a sub-image encompassing five different aquatic weed species (Eichhormia crassipes, Salvinea auriculata, Pistia stratiotes, Scirpus cubenses, Typha dominguensis)with various degrees of homogeneity and density and dead trees (paliteiros)was selected. Sar images were geometrically and radiometrically corrected and resgisteres to TM/Landasat data ERS-1 data. Preliminary results show an enhanced capability of rada data(SAR and ERS-1)for mapping the land-water boundary over water bodies affected by aquatic weed infestation. Macrophyte species, however, are better discriminated in the TM color composites. Three different species: Scirpus cubenes, Eichhornia crassipes and Salvinea auriculata were discriminated with SAR-C bands. They also proved to be useful to map the areas with different densities of dead trees (paliteiros) 91: FDB-19950515 92: FDB-MLR MFN: 6906 1: SID/SCD 2: 7649 3: INPE-7649-PRE/3499 4: SRE 5: MC 6: am 7: [07] 10: Grover,K.D. 10: Tissi, Plinio 10: Alves, A.

Visual interpretation indicated that the vegetation units of the National Forest originally delineated with RADAMBRAZIL SAR C-SAR data. Both geomorphological interpretation and visual assessment oftexture provided this additional discrimination. An evalution of class separability using the Bhattacharrya distance (BD)indicated that the ingle airborne SAR image, when included with ix Thematic Mapper reflective bands, did not ncrease class separability appreciably, ompared with six TM bands alone However, he addition of four radar channels, derived rom the original image using spatial filters and texture transformations, increased the umber of separable class pairs (BD>1.0)from 7 with the TM alone to 37. The mean increase at BD was 0.342. A comparison of the airborne hage with an ERS-1 image of the same area lowed that the airborne image was superior for delineating streams and forest clearings. However the ERS-1 image eas superior when sed to differentiate geomorphological units, cause the steeper incidence angle increased e visibility or subtle relief features.

While many of the investigations utilizing SAREX-92 data are still in progress, it is possible to generalize the findings dto date, and to apply these to plans from ERS-2 RADARSAT , and subsequest radar satellites.The discussion is arranfes by application area: natural vegetation, agriculture, geology geomorphology, hydrology, coastal applications, urban applications, and cartography. For each application we summarize the findings of investigators who participated in Canadas Tropical Forest Initiative (TFI)in Costa Rica, Brazil, Venezuela, and Guyana. From this we highlight the conclusion that may be drawn from these studies as they relate to the operational use of SAR data, paarticularly radar satellites. SAREX-92 has fostered growth in the remote sensing community towards knowledge of the capabilities and limitations of C-band SAR data in the mnoist tropics. BNased on an extensive data base and a wide variety of studies, we now know several promising tropical applications of C-band radar data, and which problems to investigate furthewr. Also important, we are in a better position both thorough technology and infrastructure to worl with resouce managers who need the information C-band SAR can offer 91: FDB-19950515 92: FDB-MLR MFN: 7045 1: SID/SCD 4: SRE 5: MC 6: am 7: [07] 10: Richey, J.

A partir das imagens e dos dados auxiliares, foi possivel, utilizando um sistema de tratamento de imagens (SITIM), um sistema de informacoes geograficas (SGI)e um sistema gerenciador de banco de dados (dBase IV), realizar a integracao destes dados multifontes e multitemporais, visando identificar as culturas agricolas. Com o intuito de avaliar os resultados obtidos pela metodologia desenvolvida, a area de estudo foi classificada digitalmente utilizando-se um algoritmo de maxima verossimilhanca. Sendo posteriormente os dois resultados comparados atraves da estatistica "KAPPA", obtendo-se indices de 0,668974 (muito bom)para o metodo de classificacao proposto e 0,472170 (bom), para metodo que utilizou a classificacao digital. Os valores obtidos permitiram cncluir que a area de estudo classificada com a metodologia proposta, obteve um indice geral de desempenho superior, em relacao a classificacao digital, de 28,93 pocento . A pesquisa alertou tambem para os problemas encontrados no momento da integracao de dados multifontes, sugerindo a utilizacao de um sistema de geoprocessamento com uma concepcao mais moderna. ABSTRACT: This work presents the development of a methodology to identify winter irrigated agricultural crops in Guaira region, State of Sao Paulo, to the year 1991, using a multitemporal imagery dataset and ground auxiliary data, covering three consecutive years (1988, 1989, and 1990)from images and auxiliary data made possible using an image treatment system (SITIM), a geographic information system (GIS), and a database management system (dBASE 4)to realize the integration of these 'multifonts' and multitemporal data to identify the agricultural crops. With the purpose of evaluating the gathered results with the proposed method, the study area was digitally classified using a likelihood algorithm. Later, both results were compared using 'Kappa statistics,' supplying the indexes of 0.668974 (very good)to the proposed method and 0.472170 (good)to the digital classification method. The gathered values showed that the classified area with the proposed method provided a general index with better performance than the digital classification, about 28.93 percent. The research also allowed the identification of problems at the moment of 'multifont' data integration, suggesting the use of a modern geoprocessing system 83: .

As combinacoes foram feitas em tanques sob iluminacao artificial controlada. Foram combinadas C. vulgaris, substancias humicas e argila (caulim). As amostras de C. vulgaris foram obtidas de culturas puras mantidas em laboratorio. Substancias humicas foram extraidas de amostras de turfa e da decomposicao de uma macrofita aquatica. Caulim foi obtido de amostras de solo. O comportamento espectral dos tres componentes foi analisado atraves das curvas de FRB, e as bandas de maior sensibilidade aos pigmentos fotossintetizantes presentes em C. vulgaris foram determinadas atraves de analise de sensibilidade e da distancia normalizada. Caulim promoveu aumento da reflectancia no intervalo de 400 a 900 nm. As substancias humicas promoveram diminuicao da reflectancia entre 400 4 670 nm, e aumento entre 670 e 900 nm. C. vulgaris mostrou faixas de aumento e faixas de diminuicao da reflectancia dependentes do revestimento interno dos tanques. As bandas de maior sensibilidade ficaram proximas dos picos de maior absorcao pelos pigmentos clorofila a e carotenoides, e ainda proximas do pico de fluorescencia da clorofila a 91: FDB-19961001 92: FDB-MLR MFN: 7487 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Lima, Reinaldo Antonio Ferreira de 18: Identificacao de processos oceanograficos superficiais, no Atlantico Equatorial, utilizando dados AVHRR 19: Identification of surface oceanographic processes on Equatorial Atlantic, using AVHRR data 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Marcio Luiz Viana (orientador); Joao Antonio Lorenzzentti; Clovis Angeli Sansigolo; Edmo Jose Dias Campos 58: SPG 59: SER 62: INPE 64: fev. <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 73: 1986/1989 76: OCEANOGRAFIA 87: TEMPERATURA DA SUPERFICIE DO MAR 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: SGI 87: SATELITES TIROS 87: AVHRR 87: RADIOMETRO AVANCADO DE RESOLUCAO MUITO ALTA 87: IMAGENS TIROS 87: MAPAS DE TEMPERATURA DA SUPERFICIE DO MAR 88: OCEAN SURFACE 88: OCEAN TEMPERATURE 88: OCEANOGRAPHY 88: GEOGRAPHIC INFORMATION SYSTEMS 88: TIROS SATELLITES 82: 83: Este trabalho tem por finalidade propor uma metodologia para transformacao dos dados de temperatura da superficie do mar (TSM), com media semanal e resolucao espacial de 18X18 Km, disponiveis no NASA Ocean Data System/Jet Propulsion Laboratory, em imagens tematicas, utilizando um Sistema de Informacao Geografica (SGI). Esta transformacao visa a identificacao dos processos oceanograficos, presentes no Atlantico Equatorial, que possuem assinatura termal superficial. Consideracoes sao feitas sobre os campos de ventos, correntes e TSM dessa regiao do Atlantico, bem como sobre a evolucao dos satelites da serie TIROS, a descricao do radiometro AVHRR e a teoria envolvida na transformacao da radiacao eletromagnetica emitida pela superficie dos oceanos em temperatura real. Os 47 arquivos semanais referentes ao ano de 1987, originalmente no formato VAX backup, foram convertidos para o padrao do sistema operacional DOS, sendo assimilados pelo SGI, onde foram geradas as imagens tematicas. Foram geradas, tambem, series de tempo de TSM para pontos selecionados, cobrindo o periodo de janeiro de 1986 a dezembro de 1989. As imagens tematicas revelaram processos oceanograficos como: o resfriamento superficial que ocorre na costa da Guine, todos os anos, semelhante a ressurgencia; o resfriamento superficial registrado ao largo da Guiana Francesa, na regiao dominada pela retroflexao da Corrente Norte do Brasil, ocorrido apenas em 1987; o aquecimento anormal, em 1987, na regiao conhecida como "Cone do Amazonas"; o aquecimento, ao largo da costa da Liberia, denominado "Domo da Guine"; a ressurgencia equatorial; e a lingua da agua fria sazonal na regiao sul do Atlantico Equatorial. As imagens tematicas revelaram oscilacoes longas nas frentes oceanograficas presentes em 05 graus N, com comprimento de 1000 350 Km e velocidade de fase de 27 11 cm/s. A analise estatistica das series de tempo representativas dessas oscilacoes conduziram a determinacao do periodo significativo, marcantemente intrassazonal, de 25 dias. A metodologia seguida permitiu aprovar um modo alternativo de gerar mapas de TSM, contornando as dificuldades normalmente encontradas em tratar imagens NOAA-AVHRR de alta resolucao 91: FDB-19970523 92: FDB-MLR MFN: 7488 91: FDB-19970523 92: FDB-MLR 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Goncalves, Silvio Manoel Silva 76: AGRONOMIA 87: COBERTURA VEGETAL 87: REFLECTANCIA BIDIRECIONAL 87: SOJA 88: CLOUD COUVER 88: BIDIRECTIONAL REFLECTANCE 88: SOYBEAN 83: O desenvolvimento de modelos de reflectancia para coberturas vegetais tem-se mostrado de grande importancia para o entendimento das relacoes existentes entre as variaveis espectrais e agronomicas, permitindo uma maior utilizacao dos dados disponiveis na area de Sensoriamento Remoto. Sendo assim, pretende-se atraves deste trabalho avaliar o desempenho dos modelos SUITS, SAIL e SRVC, bem como propor um modelo simplificado para o calculo do Fator de Reflectancia Bidirecional de coberturas vegetais (MSCR). Os dados necessarios a este estudo foram obtidos atraves de um experimento com a cultura de soja (variedade IAC-15), realizado no ano de 1991, em area experimental localizada no municipio de Paulinia, cedida pelo CPQBA (Centro Pluridisciplinar de Pesquisas Quimicas, Biologicas e Agricolas)- UNICAMP. Atraves da analise dos resultados conclui-se que, em geral, o modelo SUITS apresenta um desempenho superior ao apresentado pelos demais modelos, e que os ajustes obtidos pelos modelos estudados para a banda 4 do TM foram superiores aqueles obtidos nas demais bandas. Adicionalmente verificou-se que o modelo MSCR apresentou-se um desempenho satisfatorio, indicando a possibilidade de utilizacao de modelos simplificados para o calculo do fator de reflectancia bidirecional de coberturas vegetais. Pode-se verificar que a reflectancia difusa de folhas e o principal parametro de entrada para os modelos, sendo ela a determinante da qualidade do ajuste obtido 58: Banca: Jose Carlos Neves Epiphanio (orientador); Antonio Roberto Formaggio (orientador); Corina da Costa Freitas Yanasse; Icaro Vitorello; Luiz Roberto Angelocci 58: SPG 59: SER 62: INPE 64: fev. <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 18: Modelos de simulacao de reflectancia de dosseis agricolas para a cultura da soja (Glycine max (L.)Merr.) 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre MFN: 7489 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Faria, Kleber de 18: Proposicao metodologica para o monitoramento da distribuicao espacial da cobertura florestal aplicando tecnicas de geoprocessamento na area da ferrovia Carajas-Sao Luis 19: A methodological proposal to evaluate - the change in forest cover using a geographic information system: the case of the zone of influence of the railway carajas - Sao Luis 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Thelma Krug (orientadora); Mario Valerio Filho; Joao Roberto dos Santos; Luiz Gylvan Meira Filho 58: SPG 59: SER 62: INPE 64: jan. <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 76: VEGETACAO 87: FLORESTAS 87: MAPEADOR TEMATICO (LANDSAT) 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: SGI 87: GEOPROCESSAMENTO 88: VEGETATION 88: FORESTS 88: THEMATIC MAPPERS (LANDSAT) 88: GEOGRAPHICAL INFORMATION SYSTEMS 82: 83: Este trabalho apresenta uma proposicao metodologica para monitorar a distribuicao espacial da cobertura florestal na area de influencia da Ferrovia Carajas-Sao Luis, utilizando imagens do satelite LANDSAT (MSS e TM)e Sistema de Informacoes Geograficas (SIG).

A area de estudo foi subdividida em 427 unidades georeferenciadas na forma de uma grade. Estes valores foram incorporados a uma Planilha Eletronica, gerando taxas de alteracao da cobertura florestal em periodos distintos que, transferida para um SIG, foram analisadas tanto espacial quanto numericamente.

Os produtos utilizados para o cumprimento desses objetivos foram imagens MSS e TM/LANDSAT, HRV/SPOT, fotografias aereas, cartas topograficas e mapeamentos tematicos especificos. A area teste escolhida foi o municipio de Ubatuba, litoral norte de Sao Paulo por apresentar constantes problemas de ordem ambiental e geotecnica decorrentes da falta de criterios para a ocupacao urbana. Aos dados de expansao urbana obtidos foram integrados dados provenientes da adaptacao feita a carta geotecnica elaborada pelo IPT (1991), visando adequar o uso urbano e suas formas de ocupacao, assim como as atividades socio-economicas, as peculiaridades fisicas e ambientais do municipio. Da integracao desses dados foram gerados dois produtos cartograficos: o primeiro indicativo da expansao urbana de Ubatuba no periodo de 1973 a 1989 e o segundo indicativo das areas com diferentes tipo de restricoes a ocupacao urbana no municipio. Os resultados obtidos foram satisfatorios tanto a nivel das metodologias de sensoriamento remoto aplicadas, que contou com a aplicacao inedita da tecnica de transformacao IHS em estudos multitemporais de deteccao de alteracoes urbanas, assim como a nivel dos produtos cartograficos gerados, como subsidio ao estabelecimento de diretrizes de uso e ocupacao urbana MFN: 7494 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Almeida Jr., Almyr Cesar de 18: Avaliacao dos modelos Suits e Sail na simulacao da reflectancia espectral de dosseis de trigo (Triticum aestivun, L) 19: Evaluation of 2 canopy reflectance model for wheat (Triticum aestivum, L.) 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Antonio Roberto Formaggio (orientador); Thelma Krug; Flavio Jorge Ponzoni; Hilton Silveira Pinto 58: SPG 59: SER 62: INPE 64: dez. <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 76: AGRONOMIA 87: REFLECTANCIA ESPECTRAL 87: TRIGO 87: DOSSEL (VEGETACAO) 88: SPECTRAL REFLECTANCE 88: CANOPIES (VEGETATION) 88: WHEAT 82: 83: Objetivando coletar parametros biofisicos e espectrais para avaliar dois modelos de simulacao de reflectancia de dosseis agricolas (Suits e SAIL), foi instalado um campo experimental de trigo (Triticum aestivum, L.)em Campinas (SP). Analisaram-se as relacoes entre os parametros biofisicos e espectrais (medidos e calculados pelos modelos Suits e SAIL)e o ajuste dos modelos aos fatores de reflectancia bidirecional, para os comprimentos de onda compreendidos entre 400nm-900nm. Alem idsso, o desempenho dos modelos foi avaliado em 4 bandas simuladas do sensor Thematic Mapper (TM1-azul; TM2-verde; TM3-vermelho e TM4-infravermelho proximo). A banda TM4 obteve a melhor correlacao com os parametros biofisicos (area foliar, peso seco de folhas, indice de area foliar e biomassa). A banda TM3 foi a que obteve melhor correlacao linear dos modelos Suits e SAIL com os fatores de reflectancia bidirecional medidos no campo e entre os modelos para angulo zenital de visada a 0 e a 30 . Os modelos superestimaram sistematicamente os fatores de reflectancia bidirecional medidos nas duas configuracoes de visada, indicando uma tendencia. Os modelos Suits e SAIL, tiveram desempenho semelhante nos comprimentos de onda do visivel ao longo do ciclo fenologico do trigo. Apenas na banda TM4, as discrepancias entre os fatores de reflectancia bidirecional medidos e calculados pelos modelos foi maior no modelo Suits. Os modelos podem representar o fator de reflectancia bidirecional de um dossel desde que as caracteristicas deste dossel sejam fielmente descritas 91: FDB-19970523 92: FDB-MLR MFN: 7497 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Hamburger, Diana Sarita 18: Utilizacao de informacoes derivadas de caracterisiticas texturais de imagens orbitais na definacao de classes de uso do solo urbano 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Celina Foresti (orientadora); Gerald Jean Francis Banon; Nelson Delfino d'Avila Mascarenhas; Maria de Lourdes Neves O.

Os modelos empiricos obtidos atraves das analises de regressao linear multipla "stepwise" indicaram que os melhores resultados foram obtidos a partir dos dados simulados do sensor HIRIS, devido principalmente a localizacao e resolucao espectral das bandas selecionadas. Os modelos obtidos a partir dos dados TM/Landsat-5 apresentaram melhores resultados quando estes sao submetidos a correcao dos efeitos aditivos da atmosfera. Dentre as variaveis oticamente ativas estudadas (Total de Sedimento em Suspensao - TSS, Material Inorganico em Suspensao - MI, Material Organico em Suspensao - MO, Clorofila Total - CLTOT e profundidade de desaparecimento do disco de Secchi-Secchi), a clorofila total so foi possivel de ser modelada, a partir dos dados simulados do sensor HIRIS, atraves da razao de bandas 680 por 660 nm. Estas bandas correspondem respectivamente ao pico de fluorescencia e absorcao da clorofila 91: FDB-19970523 92: FDB-MLR MFN: 7499 58: Banca: Antonio Roberto Formaggio (orientador); Jose Carlos Neves Epiphanio (orientador); Joao Vianei Soares; Antonio Joao Lourenco 58: SPG 59: SER 62: INPE 64: jan. <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 76: AGRONOMIA 87: REFLECTANCIA ESPECTRAL 87: GEOMETRIA DE VISADA 88: SPECTRAL REFLECTANCE 83: A pesquisa teve como objetivo a avaliacao da influencia da variacao da geometria de visada no comportamento espectral da vegetacao herbacea e do substrato subjacente em pastagens compostas por Brachiaria decumbens Stapf. cv. Basilik e Brachiaria brizantha Stapf. cv. Marandu. O desenvolvimento metodologico envolveu a analise da relacao entre a reflectancia espectral e os parametros biofisicos da vegetacao herbacea e do substrato subjacente. Para tanto, foram realizadas medicoes radiometricas e biofisicas para 25 amostras da vegetacao e para uma amostra do solo em areas experimentais de 1000m2, para cada especie. As medidas de reflectancia bidirecional multiespectral (500 a 1100 nm)foram obtidas nos angulos zenitais de 0, 15, 30, 45 e 60 graus para 3 setores do plano azimutal (0,90 e 180 graus), com a variacao do angulo zenital solar controlada para uma amplitude de 10 graus (45 -55 ) e a variacao azimutal solar compensada no metodo de aquisicao. Foram avaliados os seguintes parametros biometricos da vegetacao: fitomassa total fresca e seca, fitomassa verde fresca e seca, fitomassa seca fresca e seca, teor de agua total e da fitomassa verde e seca, folhas verdes e secas, colmos verdes e secos, indice de area foliar, area foliar total, indice de cobertura, distribuicao angular das folhas estratificada por altura da cobertura e altura da cobertura. Os parametros do solo analisados foram a classificacao da cor do solo segundo a tabela Munsell, teor de materia organica, textura e rugosidade. Tal desenvolvimento visa a compreensao, em nivel quantitativo, dos principais mecanismos fisicos envolvidos na dinamica da reflectancia bidirecional multiespectral de coberturas vegetais homogeneas e suas influencias na relacoa entre os indicadores espectrais e os parametros biofisicos. O comportamento geral verificado foi coerente com o observado na literatura para coberturas completas de gramineas, sendo explicado pela atuacao conjunta dos mecanismos fisicos conhecidos como "efeito 1" (efeito geometrico da estrutura da vegetacao)e "funcao de fase" (efeito das propriedades opticas dos constituintes da vegetacao). As maiores variacoes nos valores dos FRBMs (Fatores de Reflectancia Bidirecional Multiespectral)ocorreram no plano azimutal paralelo ao plano solar, enquanto as menores ocorreram no plano perpendicular ao solar. As bandas no visivel foram as mais influenciadas pela variacao da geometria de visada, apresentando variacoes azimutais e zenitais superiores as observadas para as bandas no IVP. Para as duas coberturas nao se verificou uma influencia significativa do espalhamento anisotropico do solo na distribuicao angular dos FRBMs. O maximo conteudo de informacao sobre a estrutura geometrica da cobertura esta no AA V de 180 , que melhor se correlacionou com os parametros biofisicos, devido a ocorrencia dos picos primario e secundario de reflexao. As piores correlacoes ocorreram no AA V de 0 e estao relacionadas ao comportamento inverso da reflectancia (diminuicao)com o aumento do AZV. Os maiores coeficientes de correlacao ocorridos com a maioria dos parametros biofisicos no AZV de 45 estao associados a ocorrencia dos picos primario e secundario de reflexao proximos a esse AZV. Os parametros caracterizadores da producao e do teor de agua apresentaram as melhores correlacoes, principalmente por estarem mais relacionados a faixa do IVP, que apresentou as maiores correlacoes. O efeito geometrico da cobertura foi o mecanismo dominante, mas teve seus efeitos alterados pela atuacao do efeito da funcao de fase 91: FDB-19970523 92: FDB-MLR 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Morelli, Ademir Fernando 18: Influencia da geometria de visada na reflectancia espectral de duas gramineas forregeiras 19: The influence of view geometry variation in spectral reflectance of two forage grasses 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre MFN: 7500 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Cabral, Alexandre Pereira 18: Extracao da batimetria e dos tipos de substrato de um setor da plataforma continental do Rio Grande do Norte utilizando imagens TM-Landsat 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Marcio Luiz Vianna (orientador); Joao Antonio Lorenzzetti; Merritt Raymond Stevenson; Marcus Aguiar Gorini 58: SPG 59: SER 62: INPE 64: maio <1993> 66: Sao Jose dos Campos 67: BR 68: TDI 90: b 76: OCEANOGRAFIA 87: BATIMETRIA 87: MAPEADOR TEMATICO (LANDSAT) 87: CALIBRACAO 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: SGI 87: IMAGENS LANDSAT 87: PROJETO TOPSUB 87: SIG 88: BATHYMETRY 88: THEMATIC MAPPERS (LANDSAT) 88: CALIBRATION 88: GEOGRAPHIC INFORMATION SYSTEMS 82: 83: O presente trabalho demonstra a viabilidade de aplicacao de um metodo de extracao de batimetria e de classificacao de tipos de substrato da plataforma continental, a partir de uma unica imagem do sensor TM-Landsat, em uma ou duas bandas espectrais (banda 1 e banda 2), e de um transect batimetrico para calibracao (determinacao dos coeficientes de atenuacao da agua). A area de trabalho localiza-se em um setor da plataforma continental do Rio Grande do Norte, entre as isobatas de 10m e 30m. Empregou-se um modelo de duas bandas. Os coeficientes de atenuacao da agua obtidos foram de 0.055 m e de 0.067 m para as bandas 1 e 2, respectivamente. O erro medio na estimativa da profundidade foi de 0.92m para a banda 1 e 1.01m para a banda 2. A imagem de batimetria obtida foi fatiada em 4 classes: 10-15m, 15-20m, 20-25m e 25-30m. A imagem de tipos de substrato foi fatiada nas classes: areia, fundo misto e fundo vegetado. Um outro metodo foi testado, aplicando-se uma Transformacao por Componentes Principais (TCP)nas duas bandas mencionadas. A 1a. Componente Principal esta relacionada as variacoes de batimetria. A 2a. Componente Principal esta relacionada as mudancas do tipo de substrato. Duas imagens foram produzidas: batimetria via TCP e tipo de fundo via TCP. As imagens foram fatiadas segundo as classes mencionadas acima. Para fins de comparacao, inseriu-se no SGI-INPE os dados batimetricos de folhas de bordo da area. Os dados foram fatiados gerando-se uma imagem tematica de batimetria. O modelo de duas bandas mostrou-se mais eficiente na caracterizacao da batimetria e dos tipos de substrato. A batimetria via TCP apresentou incorrecoes, enquanto que o mapa de tipos de substrato via TCP apresentou resultados satisfatorios. As imagens de batimetria geradas pelas tres tecnicas foram relacionadas atraves de correlacoes cruzadas. A batimetria via modelo apresentou uma maior correlacao com os dados das folhas de bordo, demonstrando seu potencial para a atualizacao de cartas nauticas. O metodo e util devido a boa resolucao horizontal (30m)e vertical (1m). Os dados obtidos fornecem subsidios para o mapeamento detalhado de corpos arenosos e bancos de algas, em apoio aos trabalhos de levantamento de recursos da plataforma rasa do Nordeste brasileiro, dentro do Projeto TOPSUB da Divisao de Ciencias da Terra do INPE 91: FDB-19970523 92: FDB-MLR MFN: 7504 91: FDB-19970523 92: FDB-MLR 1: SID/SCD 4: SRE 5: T 6: m 7: [07] 16: Vedovello, Ricardo 18: Zoneamento geotecnico, por sensoriamento remoto, para estudos de planejamento do meio-fisico: aplicacao em expansao urbana 40: Pt 41: Pt 41: En 42: 50: Instituto Nacional de Pesquisas Espaciais 51: Mestre 58: Banca: Juercio Tavares de Mattos (orientador); Paulo Veneziani; Maria de Lourdes Neves O.

Entre os tipos de mapeamento geotecnico destaca-se o zoneamento para uso geral como o mais adequado para embasar estudos de planejamento sobre o meio fisico. Para a obtencao de zoneamentos geotecnicos de uso geral, a partir da interpretacao de imagens de satelite, sao identificadas tres etapas. Na primeira, e realizada uma compartimentacao fisiografica baseada na analise de elementos texturais de relevo e drenagem e de suas estruturas em imagens fotograficas. Assim, sao identificados unidades basicas de compartimentacao (UBCs)as quais estao incluidas em niveis taxonomicos mais gerais (Provincia, Zona e Subzona). Na segunda, as UBCs obtidas na primeira etapa sao caracterizadas em funcao de fatores (propriedades e caracteristicas)geotecnicos considerados basicos para subsidiar a avaliacao das unidades quanto ao potencial de uso para expansao urbana. Ja na terceira etapa, a partir de uma tabela de correlacao entre os fatores analisados e o potencial de uso, as unidades basicas de compartimentacao sao classificadas segundo quatro classes de aptidao/restricoes. A avaliacao dos resultados obtidos mostrou que o procedimento adotado apresenta grande potencial para aquisicao de zoneamentos geotecnicos subsidiarios a estudos de planejamento do meio fisico e de analise ambiental. Alem disso, o formato das UBCs possibilita o uso dessas unidades nao so para o zoneamento geotecnico como para quaisquer tipos de estudos que versam sobre a avaliacao de terrenos MFN: 7513 1: SID/SCD 2: 5346 3: INPE-5955-NTC/320 4: SRE 5: S 6: as 7: [07] 10: Banon, Gerald Jean Francis 10: Barrera, Junior 12: Decomposition of mappings between complete lattices by mathematical morphology, part I.

These decompositions are based on mathematical morphology elementary mappings: erosions, anti-erosions, dilations and anti-dilations. The proposed decompositions are obtained by introducing the concept of morphological connection, that extends the notion of Galois connection. The definitions of sup-generating mapping, kernel and basis within the framework of complete lattices are given. The decompositions are built by analysing the kernel and may be simplified from the basis. The results are specialized to the cases of inf-separable, increasing and decreasing mappings. The presented decompositions are dual. Some examples, including the case of boolean functions simplification, illustrate the key concepts and the decomposition rule 91: FDB-19970605 92: FDB-MLR MFN: 7692 1: SID/SCD 2: 6369 3: INPE-6369-PRE/2443 4: SRE 5: MC 6: am 7: [07] 10: Bins, Leonardo Sant'Ana 10: Erthal, Guaraci Jose 10: Fonseca, Leila Maria Garcia 12: Um metodo de classificacao nao supervisionada por regioes 14: 65-68 21: v.4 40: Pt 41: Pt 42: 53: Simposio Brasileiro de Computacao grafica e Processamento de Imagens, 6 54: 19-22 out. <1993> 56: Recife 58: DPI 61: 64: <1993> 68: PRE 90: b 88: CLASSIFICACAO 88: CLUSTERING 88: SEGMENTATION 88: STATISTICS 83: A clustering classification method is described and applied to Landsat TM images.

In an effort to develop this area of applications, we have investigated the use of a number of C-band SAR data sources to detect openings in moist tropical forests. The smallest openings, typically 0.25 to 3 ha in size and are often associated with shifting cultivation, were reliably detected with 7-look airborne SAR with 6 m resolution in range and azimuth. Openings in the range 1 - 10 ha in area, associated with settlements in extractive reserves in Brazil were also reliably detected with the high resolution airborne data. These small openings were not visible on simulated or actual satellite SAR images with four looks and 25 to 30 m resolution. Agricultural settlement projects typically create many contiguous openings which total 100 to 1000 ha or more in area. These were reliably detected with both airborne and satellite images. However, mapping of boundaries was found to be much more accurate with the higher resolution airborne data than with the actual and simulated satellite data. Land clearing for cattle ranching creates large rectangular openings of 1000s of ha in size. These clearings were, in general, reliably detected and mapped with all of the data sources evaluated. However, detection and mapping with satellite SAR data is more difficult while the land is still in the process of conversion to pasture, and again when it is overgrown at an early stage of primary succession. Under these conditions, the average backscatter from the cleared land is often similar to that of the surrounding forest. This finding indicates that the most reliable mapping of clearings may be possible if radar data is acquired annually, to detect each pasture in its "clean pasture" stage when it has the highest contrast with its surroundings. There is a tendency to underestimate the area of clearings using SAR data alone. However, optical satellite data can be used to produce a regression model to remove much of this systematic error 91: FDB-19970728 92: FDB-MLR MFN: 7707 1: SID/SCD 2: 6356 3: INPE-6356-PRE/2432 4: SRE 5: MC 6: am 7: [07] 10: Camara Neto, Gilberto 12: Anatomia de sistemas de informacoes geograficas: visao atual e pespectivas de evolucao 14: 15-37 40: Pt 41: Pt 42: 53: Sistema de Informacoes Geograficas: aplicacoes na agricultura 58: DPI 61: 62: EMBRAPA 64: <1993> 66: Planaltina 67: BR 68: PRE 90: b 71: LIVRO 76: ENGENHARIA DE SISTEMAS COMPUTACIONAIS 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: SGI 87: CARACTERISTICAS 87: EVOLUCAO 83: A caracteristica fundamental de um sistema de geoprocessamento e sua faculdade de armazenar, recuperar e analisar mapas num ambiente computacional. Um mapa e uma representacao grafica de fenomenos geograficos, geralmente em uma superficie plana. Num ambiente computacional, a nocao de mapa deve ser estendida para incluir diferentes tipos de dados geograficos, como imagens de satelite e modelos numericos de terreno (MNTs). Em resumo, as principais caracteristicas dos sistemas de informacoes geograficas (SIGs)sao a possibilidade de: - integrar, numa unica base de dados, as informacoes espaciais provenientes de dados cartograficos, dados de censo e de cadastro urbano e rural, imagens de satelite, redes e MNTs; - combinar as varias informacoes atraves de algoritmos de manipulacao, para gerar mapeamentos derivados; - consultar, recuperar, visualisar e desenhar o conteudo da base de dados geocodificados. Os dados tratados em SIGs incluem imagens de satelite, MNTs, mapas tematicos, redes e dados tabulares. Uma caracteristica basica e geral num SIG e a sua capacidade de tratar as relacoes espaciais entre os objetos geograficos. Denota-se por topologia a estrutura de relacionamentos espaciais (vizinhanca, proximidade, pertinencia)que podem se estabelecer entre objetos geograficos. Armazenar a topologia de um mapa e uma das caracteristicas basicas que fazem um SIG se distinguir de um sistema CAD (Computer Aided Design). A outra diferenca fundamental e a capacidade de tratar as diversas projecoes cartograficas. Como ambientes CAD nao guardam a topologia dos objetos representados, SIGs que evoluiram a partir destes (como o GeoSQL e o MGE/Intergraph)armazenam os dados em formato vetorial, sem guardar a topologia. A entrada de dados e mais facil; o armazenamento e a recuperacao, menos eficientes. Para aplicacoes em analise geografica e em redes, o armazenamentto da topologia permite o desenvolvimento de consultas a um banco de dados espacial, que nao seriam possiveis de outra maneira 91: FDB-19970728 92: FDB-MLR MFN: 7708 1: SID/SCD 2: 6357 3: INPE-6357-PRE/2433 4: SRE 5: MC 6: am 7: [07] 10: Felgueiras, Carlos Alberto 10: Camara Neto, Gilberto 12: Sistema de informacoes geograficas do INPE 14: 41-59 38: (Livro) 40: Pt 41: Pt 42: 53: Sistemas de informacao geografica: aplicacoes na agricultura 58: DPI 61: 62: EMBRAPA 64: <1993> 66: Planaltina 67: BR 68: PRE 90: b 71: LIVRO 76: ENGENHARIA DE SISTEMAS COMPUTACIONAIS 87: SISTEMAS DE INFORMACAO GEOGRAFICA 87: GIS 87: SIG 87: SGI 87: CARACTERISTICAS 87: SITIM 87: SISTEMA DE TRATAMENTO DE IMAGENS 83: O desenvolvimento de sistemas computacionais para aplicacoes graficas e de imagens vem influenciando de maneira crescente as areas de Cartografia, de Mapeamento, de Analise de Recursos Naturais e de Planejamento Urbano e Regional. Esta tecnologia automatiza tarefas realizadas manualmente e facilita a realizacao de analises complexas, atraves da integracao de dados de diversas fontes e da criacao de um banco de dados geocodificado. Os sistemas para tal fim sao denominados de Sistemas de Informacoes Geograficas (SIGs). Num pais de dimensao continental como o Brasil, onde existe uma grande carencia de informacoes adequadas para a tomada de decisoes sobre problemas urbanos e ambientais, tais sistemas apresentam um enorme potencial, principalmente se forem baseados em tecnologias de custo relativamente baixo e se todo o conhecimento for adquirido localmente. Para atender a estas necessidades, foi desenvolvido, na Divisao de Processamento de Imagens (DPI)do Instituto Nacional de Pesquisas Espaciais (INPE), o sistema SGI. Esse sistema utiliza ambiente de microcomputadores, compativel com a linha IBM-PC, sob sistema operacional DOS. Este capitulo descreve as caracteristicas e os conceitos importantes para o entendimento do SGI versao 2.4. O capitulo mostra tambem a forma de relacionamento do SGI com o banco de dados relacional dBASE IV, com o sistema de tratamento de imagens SITIM, com outros sistemas de apoio a desenhos (CADs)e com outros SIGs. As caracteristicas importantes do SGI, assim como uma descricao detalhada da sua funcionalidade e de sua estrutura geral tambem estao incluidas. O SGI e um banco de dados geograficos que permite adquirir, armazenar, combinar, analisar e recuperar informacoes codificadas espacialmente. O SGI contem, na sua quase totalidade, funcoes implementadas em linguagem C. Apenas algumas funcoes de nivel mais baixo, que exploram as caracteristicas do "hardware", foram desenvolvidas em linguagem ASSEMBLER. Atualmente o SGI esta na sua versao 2.4. O SGI e um sistema orientado por menus com uma grande preocupacao com a facilidade de uso do sistema, sugerindo, inclusive, valores "default" a cada interacao de um aplicativo com o usuario. Os principais objetivos do SGI sao: - integrar, numa unica base de dados, informacoes espaciais provenientes de dados cartograficos, de dados de censo, cadastro urbano e rural de imagens de satelite e de modelos numericos de terreno (MNTs)(incluindo topografia, dados geofisicos e geoquimicos); - combinar as varias informacoes, atraves de algoritmos de manipulacao, para gerar mapeamentos derivados; - reproduzir, visualizar e plotar o conteudo da base de dados geocodificados. O INPE desenvolveu tambem o SITIM, que e um sistema de tratamento digital de imagens de sensoriamento remoto. O SITIM esta implementado no mesmo ambiente computacional do SGI. Qualquer imagem trabalhada no SITIM pode ser utilizada diretamente pelo SGI. O SGI possui uma interface direta com o banco de dados relacional dBASE IV, onde se pode armazenar atributos para os elementos geograficos do SGI. Esses atributos ficam integrados totalmente aos elementos geograficos e, portanto, podem ser usados para analises ou classificacoes das informacoes do SGI 91: FDB-19970728 92: FDB-MLR MFN: 7753 1: SID/SCD 2: 6411 3: INPE-6411-PRE/2451 4: SRE 5: S 6: as 7: [07] 10: Pellerin, J. 10: Pouget, J. 10: Valerio Filho, Mario 10: Santana, M.A 12: Metodologia de utilizacao de dados espaciais Landsat MSS e TM no estudo de uso do solo: regiao de Marilia, SP 14: 79-97 30: GEOSUL 31: 16 32: 8 40: Pt 41: Pt 42: 58: DSR 61: 64: <1993> 68: PRE 90: b 83: Sao apresentados resultados de tratamentos de imagens Landsat MSS e TM de estacao umida e estacao seca da regiao de Marilia. Inicialmente foram classificadas imagens MSS pelo metodo dos hipercubos utilizados no ORSTOM (Bondy, Franca). Cerca de quinze temas foram buscados, alguns nao apresentando problemas de identificacao, mesmo em modo monotemporal (florestas, solo nu e superficies urbanizadas perfeitamente diferenciadas em estacao umida). Os resultados sobre a cana-de-acucar e as classes de pastagens sao melhores em estacao seca, enquanto outros so puderam ser separados por tratamentos multitemporais (cafe, diversas pastagens, culturas anuais). Os dados TM (visivel, infra-vermelho proximo e medio)exploram as contribuicoes fornecidas de uma parte por uma maior resolucao espacial, d'outra parte pela contribuicao dos canais 5 e 7. Os principais resultados obtidos a partir duma imagem de estacao seca foram: - a contribuicao da resolucao espacial, capital para uma regiao onde as parcelas sao relativamente pequenas e o relevo contrastado. As composicoes mais interessantes foram, em ordem decrescente: 7-5-4 e 1-4-5 associadas, 2-3-4, e 1-2-3; - o acesso a heterogeneidade das parcelas ou grupos de parcelas obriga a efetuar classificacoes sobre zonas reduzidas, atraves de mascaramento com um zoneamento em funcao das unidades geomorfologicas; - a interpretacao e a utilizacao completa de dados TM nao podem ser efetuadas senao atraves de um conhecimento aprofundado do campo e exige assim observacoes permanentes; - a utilizacao de tratamentos multitemporais e o desenvolvimento de novos tratamentos, tais como testes de textura, permitem avancar na identificacao de diferentes tipos de uso do solo.

This process induces a lot of inadequate land use/cover for the rural environment. The intensification of agricultural activities may result in increasing erosion processes and acelerated soil losses, threatening naural resources integrity, mainly water quality, and the productivity of agricultural systems. In this context the knowledge of potential erosion of specific soil groups is very important to support agricultural and environmental planning. This study was undertaken in an agricultural watershed (Eastern area of Sao Paulo State-Brazil)and its purpose was to evaluate the Natural Erosion Potential (NEP)to provide information for rural planning. This work presents an approach on the use of remote sensing and GIS- Geographic Information Systems technology applied to survey and data integration of a small watershed. The parameters from the Universal Soil Loss Equation - USLE, such as erosivity, erodibility, slope length and steepness, obtained from ancillary data or calculated, were integrated within a GIS (INPE/SIG). The results allowed the calculation of the natural erosion potential for the watershed. TM-Landsat data (CCT)were digitally analyzed, and a map on land use/cover was obtained (parameter C of USLE). The erosion susceptibility map was obtained from tolerable soil losses and land use data. This map provided further information to elaborate the management plan for this watershed 91: FDB-19990317 92: FDB-MLR MFN: 8542 1: SID/SCD 2: 7194 3: INPE-7194-PRE/3109 4: SRE 5: MC 6: am 7: [07] 10: Santos, Marcos Verdi 10: Crossetti, Mario 10: Weber, Eliseu 12: Utilizacao de imagens do satelite Landsat TM na estimativa de areas cultivadas com arroz irrigado 14: 33 18: Resumos 40: Pt 41: Pt 42: 52: SBA 52: UFRGS 52: UFSM 53: Congresso Brasileiro de Agrometeorologia, 8 54: 27-30 jul. <1993> 56: Santa Maria 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 87: ARROZ 87: IRRIGACAO 87: MAPEADOR TEMATICO (LANDSAT) 87: IMAGENS LANDSAT 87: SATELITES LANDSAT 87: SITIM 87: SISTEMA DE TRATAMENTO DE IMAGENS 87: PROJETO OTICO PROCOM-2 82: 83: 0 conhecimento das areas cultivadas com as diferentes -culturas agricolas e essencial para o planejamento da agricultura e as atividades economicas decorrentes.

A area estudada foi do municipio de Itaqui-RS, com uma superficie de 5.130 Km2. 0 trabalho foi realizado no CEPSRM/UFRGS utilizando os equipamentos SITIM-150, SGI e o projetor otico PROCOM-2. Foram interpretadas imagens coloridas em transparencia positiva (3B-4G-5R)de 4 anos/safra(84/85, 85/86,86/87 e 87/88)da cultura do arroz irrigado, tendo em media 3 imagens por safra . A interpreta‡ao foi feita em escala 1:50.000 com base nas Cartas do Servi‡o Geografico do Exercito e as areas calculadas por digitaliza‡ao. Os resultados mostraram uma consideravel diferen‡a entre as estimativas dos orgaos oficiais, que foram sempre menores em rela‡ao a obtida pela interpretacao das imagens de satelite. A compara‡ao das areas estimadas pelas imagens de satelite e as obtidas por medidas a campo mostrou um coeficiente de regressao de 0,93, o que demonstra a boa precisao da metodologia testada e a possibilidade de utilizacao de forma operacional 91: FDB-19990825 92: FDB-MLR MFN: 8543 1: SID/SCD 2: 7195 3: INPE-7195-PRE/3110 4: SRE 5: MC 6: am 7: [07] 10: Silva, Bernardo Barbosa 10: Rao, Tantravahi Venkata Ramana 10: Azevedo, Pedro Vieira 10: Souza, Cleber Brito 10: Epiphanio, Jose Carlos Neves 12: Caracteristicas espectrais do algodao herbaceo irrigado e sob estresses hidrico 14: 107 18: Resumos 40: Pt 41: Pt 42: 52: SBA 52: UFRGS 52: UFSM 53: Congresso Brasileiro de Agrometeorologia, 8 54: 7-30 jul. <1993> 56: Santa Maria 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 87: ALGODAO 87: IRRIGACAO 87: REFLECTANCIA 87: ESTRESSE HIDRICO 87: INDICE DE AREA FOLIAR 87: MAPEADOR TEMATICO (LANDSAT) 87: IMAGENS LANDSAT 87: SATELITES LANDSAT 82: 83: A identificacao de culturas mediante tecnicas de sensoriamento remoto requer informa‡oes acerca da verdade terrestre do alvo de interesse. Neste sentido torna-se imperioso que se conhe‡am as caracteristicas espectrais de alvos, que no caso foi o algodao herbaceo e o solo da area cultivada. 0 local do experimento foi Ipangua‡u-RN, e utilizou-se um espectrorradiometro da SPECTRON que opera em 252 bandas do espectro eletromagnetico, situadas entre 350 e 1150 nanometros. No estudo foram consideradas duas parcelas com 30m X 30m, cultivadas com o algodao herbaceo (Gossypium hirsutum r. latifolium)variedade 6H, e sumetidas a dois tratamentos de irrigacao. Foram obtidas varias baterias de medi‡oes entre os dias 5, 6 e 7 de novembro de 1992. As analises dos espectros da cultura e do solo, revelaram que as diferen‡as situam-se nos valores da reflectancia e nao no formato dos espectros. No TM4, a reflectancia da cultura nao estressada foi cerca de 60 83: , enquanto a estressada situou-se por volta de 50 83: Os espectros do solo evidenciaram um mesmo comportamento (seco ou Molhado, ambos sem cobertura vegetal), porem a reflectividade do solo seco mostrou-se bem mais Pronunciada, em todas as bandas TM1, TM2, TM3 e TM4. SUgere-se que as diferen‡as entre os tratamentos se devem mais as diferen‡as no IAF do que no estado de turgescencia das folhas da cultura com e sem estresse 91: FDB-19990825 92: FDB-MLR MFN: 8544 1: SID/SCD 2: 7196 3: INPE-7196-PRE/8544 4: SRE 5: MC 6: am 7: [07] 10: Santos, Marcos Verdi 10: Moreira, Mauricio Alves 10: Weber, Eliseu 12: Estudo do comportamento espectral da cultura do arroz irigado 14: 131 18: Resumos 40: Pt 41: Pt 42: 52: SBA 52: UFRGS 52: UFSM 53: Congresso Brasileiro de Agrometeorologia, 8 54: 27-30 jul. <1993> 56: Santa Maria 57: BR 58: DSR 61: 64: <1993> 68: PRE 90: b 76: AGRONOMIA 87: ARROZ 87: IRRIGACAO 87: MAPEADOR TEMATICO (LANDSAT) 87: IMAGENS LANDSAT 87: SATELITES LANDSAT 87: COMPORTAMENTO ESPECTRAL 87: SITIM 87: SISTEMA DE TRATAMENTO DE IMAGENS 82: 83: 0 presente trabalho foi conduzido com o objetivo de estudar o comportamento espectral da cultura do arroz irrigado nas condicoes de cultivo da fronteira oeste do Rio Grande do Sul. 0 trabalho foi realizado com imagens em fitas CCTïs do satelite Landsat TM de dois anos safra (87/88 e 88/89)com, respectivamente, seis e oito imagens uteis durante o ciclo da cultura. As informacoes de campo foram baseadas em uma area piloto de 795 ha, dividida em 32 sub-areas de cultivo, localizada no municipio de Uruguaiana-RS. O processamento e tratamento das imagens foi feito utilizan-do-se o equipamento SITIM-150. Foram analisadas as respostas espectrais da cultura nas 14 datas de passagem do satelite e feita a associacao com as praticas culturais desenvolvidas em cada uma das 32 sub-areas de cultivo. Dentre as praticas culturais a de maior influencia na resposta espectral da cultura foi a irrigacao por inundacao. As bandas do satelite de maior contribuicao para identificacao da resposta espectral foram a TM3, TM4 e TM5, sendo que a TM5 e a que mais contribui para identificacao da cultura. O comportamento espectral da cultura no mes de fevereiro e o mais homogeneo e o que mais contribui para a identicacao e classificacao da cultura 91: FDB-19990825 92: FDB-MLR MFN: 8879 1: SID/SCD 2: 7942 3: INPE-7942-PRE/3777 4: SRE 5: MC 6: am 10: Casanova, M. 10: Hemerly, A 10: Duarte, M.P.C. 10: Mediano, M.R. 10: Camara Neto, Gilberto 10: Freitas, Ubirajara Moura 12: Um gerenciador para atributos espaciais de objetos geograficos 14: 223-238 18: Anais 40: Pt 41: Pt 42: 53: Simposio Brasileiro de Geoprocessamento 54: jul. <1993> 56: Sao Paulo 58: DPI 61: 64: <1993> 68: PRE 90: b 76: GEOPROCESSAMENTO 87: ARQUITETURA 87: BANCO DE DADOS 87: GERENCIADOR 88: ARCHITECTURE 88: GEOGRAPHIC DATABASE MANAGEMENT 83: Uma arquitetura para sistemas de gerˆncia de bancos de dados geograficos e inicialmente delineada.

Examples occur in scale magnification, image registration, geometric correction, etc. On the other hand, this image can be subject to several sources of degradation and it would be interesting to compensate also for this degradation in the interpolation process. Therefore, this article addresses the problem of combining interpolation and restoration in a single operation, thereby reducing the computational effort. This is done by means of two-dimensional, separable, Finite Impulse Response (FIR)filters. The ideal low pass FIR filter for interpolation is modified to account for the restoration process. The Modified Inverse Filter (MIF)and the Wiener Filter (WF)are used for this purpose. The proposed methods are applied to the interpolation-restoration of L-andsat-5 Thematic Mapper data. The later process takes into account the degradation due to optics, detector and electronic filtering. A comparison with the Parametric Cubic Convolution (PCC)technique is made. The experimental results consist of interpolation-restoration processes of Landsat-5 Thematic Mapper images from 30m to 15m (scale magnification)but they could also be generalized to include deblurring on more general interpolation problems, like geometric correction 91: FDB-20010305 92: FDB-MLR MFN: 9877 1: SID/SCD 2: 8928 3: INPE-8928-PRE/4631 4: SRE 5: MC 6: am 7: [07] 10: Paradella, Waldir Renato 10: Vitorello, Icaro 10: GalvÆo, Lenio Soares 12: Discrimina‡Æo de lateritas mineralizadas em fosfato e titƒnio no complexo alcalino-ultram tico de Maicuru (PA), atraves de t‚cnicas de sensoriamento remoto 14: 998-1002 18: Anais 40: En 41: En 42: 53: Congresso Internacional da Sociedade Brasileira de Geof¡sica, 3 54: <1993> 58: DSR 58: DGE 61: 64: <1993> 76: GEOLOGIA 83: Mineralized laterites developed over the Maicuru alkaline-ultramafic-carbonatite Complex are distinguished inenhanced remote sensing orbital products. The Maicuru structure is located in the intractable tropical forest of the Amazon (state of Parg, Brazil). Deep lateritic weathering resulted in the formation of lateritic duricrusts, lateritic soils, Alluvium and talus. The remote sensing discrimination of several units is only possible because of associations of vegetation cover and the superficial lithology. Magnetic ferruginous duricrust occurs in the northern part of the intrusive and supports the "Cerrado", a savanna type vegetation. Open grasslands on rocky grounds ("campos rupestres")are found over a duricrust which has a large portion of it enriched in anatase. The remaining differentiated units are aluminous phosphatic laterites, alkaline latosols and colluvium, covered by tropical forest
