The IBGE Foundation and the Government of the Para State in Brasil represented by Secretary's Office for Industry, Trade and Mining (SEICOM), are executing studies for the elaboration of the Masterplan on Mining in Belim Metropolitan Region. In the first stage of this studies will be identified the environment systems by the correlation between nature - including rocks, relief, vegetation, soils, water and air -, and society - including land use and socioeconomics activities. The basic materials used for obtainable these informations are the images from Thematic Mapper sensor of the LANDSAT-5 satellyte, on the bands 3, 4 and 5. The images was analysed by Digital Processing, utilizing the hardware and software of the Images Treatement Systems (SITIM), developed by INPE/ENGESPAGO society, on the laboratories of the Hidroclimatology and Remote Sense Center of Amazonia (CHSRA) of the Superintendence for Development of Amazonia (SUDAM). This Work describe the digital processing tecniches utilized, whose objective was to get better the quality of the images to the visual interpretation and to establish identification patterns of the degraded areas by mining in the Belim Metropolitan Region and neigbornhood. The tecniches utilized was: image transference tape-hard disk, dysplay of images, color compositions, and relief of images including stretch, spacial filtering and spectral rotatioh. We conclude that the best image for our objectives was the color composition 5R 4G 3B reliefed by linear stretch.Pages: 167-17
