| Summary: | There are several procedures of spatialization and individualization of physical environmental units, such as the techniques
of remote sensing and geoprocessing. The physiographic compartmentation can be performed by systematic photointerpretation processes of satellite images, trough the analysis of the drainage network’s properties, from the homogeneity and
similarities of landscape units. The advantage of applying this technique in environmental planning is the generation of a
single cartographic product sectioned into several landscape units, which summarize characteristics of relief, geology and
land use. This study aimed at making the physiographic compartmentation in Casa Branca, São Paulo state, based on the integration of data from analysis of satellite images, mapping products, and geological and geomorphological data. The city
suffers problems related to lack of urban planning and the development of erosive processes. Analyzing the results, it was
concluded that the methodology adopted for the research was very efficient. Therefore, it is expected that this research may
support the decisions of urban planning in the city and that the described procedures can be the basis for the development
of geo-environmental zoning in other municipalities. |
