Abstract

This work presents a semiautomatic proposal for elaboration of Morfometrical Map (Declivity, Horizontal Dissection, Vertical Dissection and Relief’s Energy) with the assistance of Auto CAD and SGI IDRISI softwares. It discusses in details, the technical - methodological processes involved, as well as the eventual limitations and generalizations presented by the softwares in the related methodology. The results were obtained through the quantification on an 8km² sampling from the original area (Sub - basin of “Araras’s Rivers”) inserted as integral part of 7th UGRHI (Unit of Water Resources Administration - State of São Paulo). The final considerations that accompanies the development of the work, emphasizes a technical appropriated methodology (in relation to the conventional one), generating Morfometrical Maps of the relief with gains of functioning, agility and easy quantification of data. Keywords: Digital Cartography; Morphometrical Map; Geomorphology; SGI; AutoCAD MAP.
