The recognition, understanding and relief delineation are of great importance to underpin the actions of planning and environmental and land management, and geomorphological mapping an important tool to support engineering projects dealing with issues related to the organization, planning and management of geographic space , whether urban or rural. The demand for obtaining relief data is growing, but the conventional method is costly and time consuming as it involves extensive field work. Advances in the field of computer potentiate the use of digital techniques favored the generation of Digital Elevation Models (DEM) containing height information and elevation of all objects present on the earth's surface. The use of such models allows the study of a particular phenomenon without the need to work directly on the area. With this approach, the present study was dedicated to demonstrate the application of the EAW derived from geomorphometric Database Brazil (TOPODATA) with spatial resolution of 30 meters, for the generation of cartographic documents containing: contours, slope and hypsometry, generation of topographic profile and longitudinal profile through the use of Global Mapper GIS software and Google Earth Pro, the basin of the river Ocoy, located in the west of Paraná state. Through Global Mapper software tools, it was possible to simulate a flood dam in the basin, demonstrating the EAW potential for environmental analysis and engineering projects. |
