ResumoThis study describes the procedure used to identify zones considered to be homogeneous on the basis of the physical characteristics of the terrain interpreted on Landsat TM images. The study was carried out on the upper-middle Paraiba do Sul river region, State of Sao Paulo, Brazil, and took into account the main characteristics of the physical environment (geology, physical geography and soils). The study took into account data from laboratory analysis of soils and rocks in reference to their physical, chemical and mineralogical characteristics of samples from soil profiles, as well as edaphoclimatic information and morphostructural anomalies. The geoenvironmental zones present the technical evaluations of water resources (surface and underground), land use, regional planning, environmental issues, etc. From these informations about geoenvironmental zones, was carried out the methodology of values ponderation, using SIG through the Fuzzy technique and the Analytical Hierarchy Process – AHP. The results are presented as a map of physical characteristics as support for highway planning.
