| Abstract | En este trabajo, se presentan algunas soluciones simples para Ias principales dificultades que enfrentan los usuarios de técnicas digitales de detección de cambios. Aunque estas soluciones tienen aplicacióri general, se hace énfasis en Ia cobertura vegetal dei semiárido. Los pasos metodológicos mejorados en este trabajo están relacionados con; selección de una banda espectral adecuada para cada fin, una nueva técnica de detección de cambios y transfonnación de Ia imagen detección de cambios para obtener el mapa temático, a través dei seccionado y rotulado. Cada uno de estos pasos son mejorados modificândolos e introduciéndoles alguna innovación técnica. Una evaluación de Ia situación actual indica que en el mismo ambiente técnicas diferentes producen resultados diferentes. Estas diferencias son producidas por Ias dificultades encontradas para compatibilizar radiometricamente los datos adquiridos en fechas diferentes. Se obtuvo el mapa de detección de cambios con buena exactitud y con buena correspondencia en Ia detección de formas y patrones de uso. La rotación controlada permite eficiencia sin complicados preprocesamientos (calibraciones radiométricas y correcciones atmosféricas), permítiendo utilizar en forma accesible imágenes obtenidas con diferentes sensores, siempre que sean conipatibilizadas sus resolución espacial. --> ABSTRACT: In this work some simple solutions for the main difficulties are presentedIdisplayed that face the users of digital teclíniques of detection of changes. Although these solutions have general application, ín thís work becomes emphasis in the vegetal cover of the region of the serni-arid one. The methodologic improvements were done in the selection of an suitable spectral band for each aim, creating a new teclínique of detection of changes and ímproving the sectioned one and labeled of the image detectíon of changes for its transformation in thematic map. Each one of these steps is iniproved modifying them or introducing some technical innovation to them. When one evaluates the present conditions of the teclíniques, it is observed that in the same landscape different tecimícal they produce díffèrent results. These dífferences are produced by the difficulties radiometricaíly to make compatible the data collected in different dates. The map of detection of changes with good exactitude and good correspondence in the detection of forms and patterns of use was obtained. The controlled rotation allows efficíency wíthout cornplícated pre-processings (radiornetric calibrations and atmospheric corrections), allowing to use in aecessible form images obtained with different sensors, whenever their space resolutions are made compatible. |
