The objective of this study is to prepare a geomorphological map of a section of the Rio Paraiba do Sul watershed in the surroundings of São José dos Campos City (São Paulo State) using remote sensing and GIS techniques. Color composite LANDSAT-TM images from both January (1987) and July (1988) were analyzed according image texture, shape, shadow and pattern characteristics. The landform units of this region were classified as denudational (hills and ridges) and depositional units (fluvial plains and terraces). The three types of interfluve: flat, round and angular can be distinguished on these images. GIS techniques such as algebra map were applied to obtain two morphometric indices: interfluve and relief amplitude. These parameters were calculated using the zonal operators implemented under the environment of the command language of the SPRING system (LEGAL). The result is a map of homogeneous landform units of the area under study.
