This study proposes the use of images in raster format project - TOPODATA / INPE, which can be applied in the study of geomorphological boundaries of watersheds. The objective is to evaluate the generation of preliminary data to aid the study of the natural fragmentation of the watershed's landscape Pericuma, inserted in the Brazilian Amazon. Thus, it can be seen that the results presented here contradict previous studies in the area. Previous to this study showed that the elevations reached the maximum 50 meters. Already the boundaries of the watershed of Pericuma and the drainage network of water bodies semiautomatically generated, have become loyal information previously processed in the laboratory and confirmed in the field.359-376porLand surfaceWatershedTOPODATATrabalho apresentado em evento10.14195/978-989-26-0983-6_20WOS:000467013600021Acesso aberto5110893809183033
