Abstract

This paper intends to demonstrate the relevance of cartography in river basins studies, remarking the efficiency and agility in maps elaboration, when processed in digital media. The cartography map is the main base of information for the river basin research. For this purpose, the fundamental elements which for its mathematic base (of proportion, systematization and reference), the planimetrical elements (hydrography, vegetation etc.) and the altimetrical elements (contour lines and altitudes)are put forwarded. Essential morphometrical informations are obtained usually from altimetry such as the declivity, hypsometry among others. These informations are obtained in digital media with quickness and precision making more agilely the process of elaborating morphometrical maps. Keywords: Topographical map, river basin, morphometry, digital cartography
