RESUMO

This study presents a terrain zoning to characterize, hierarchize and quantify its capability to the urban development, considering the physics, biological and anthropic regional aspects. The study area size is 120 sq km and it takes part of the Una river basin, in the Sao Sebastiao county, located in the North Litoral of São Paulo state, Brazil. The study was developed into two parts: in the first one, it was developed thematic maps, by using satellite images, digital image processing techniques and cartographic data, in the second one it was used a Geographical Information System, to build up a data base to integration and spatial analysis. The GIS used was the SPRING and the data base was composed by satellite images, maps such as geomorphological map, geological map, declivity map, land use map, fractures isofrequency map, transport capability map, permeability map and erosion resistance map. It were used LANDSAT/TM Images, bands 3, 4 and 5 in several formats such as digital, analogical and slides. The study scale was 1:50,000.ln the satellites images it was possible to identify characteristics and terrain features not propitious to urban development. Besides a temporal satellite images analysis showed a tendency to the populational growing in the study area. In the study are suggested some proceedings that have to be done in order to minimize the human degradational effects in the real urbanization process.
