                         work analyzes the use of AVHRR/NOAA images to detect and evaluate 
                         deforestation in the Amazon Forest using TM/Landsat images for 
                         validation and calibration of the results. A pilot methodology was 
                         developed for the region of {"}Serra do Roncador{"}, MT, where 
                         deforestation is caused by large agriculture and cattle projects. 
                         An AVHRR image with spatial resolution of 2 km and geometrically 
                         corrected was used to classify areas of deforestation and forest. 
                         The identification of these classes and the comparison and 
                         validation of the area estimates with the visual interpretation of 
                         the TM/Landsat images were based and on the use of Geographical 
                         Information System. The results of forest and deforestation areas 
                         obtained from AVHRR were compared to TM data using statistical 
                         analyses and strong linear correlation and regression were found 
                         between the data sets (R2 = 0.93). An application of the model for 
                         the region of S{\~a}o Jos{\'e} do Xingu, MT, with a 
                         deforestation pattern similar to that found in the first region, 
                         presented adequate results with average erros of 3% for the total 
                         forest area. The results corroborated the use of AVHRR band 3 to 
                         detect and monitor alterations in forestes areas. TM/Landsat data 
                         are necessary to calibrate estimates of areas.",
