Conteúdo: 	ABSTRACT: The necessity of creating a main plan for national parks is necessary for the technique's improvement for a better understanding of the environmental factors thar interfere in the conservation of these units. In this context, image processing techniques are important tools in this characterization. In this paper, we describe the use of the terrain Digital Elevation Model (DEM) as a tool for the description of the geological and geomorphological's characteristics from the Chapada dos Veadeiros National park, that has 60,000 ha and it is located in Cavalcante town and Alto Paraíso de Goiás town (GO). By the visual analysis of the DEM is very clear the relief forms that furnish a strong aid to the understanding of the distribuition of the geomorphological and geological units and indirectly of the vegetation. With the use of the maps from the DEM such as the hypsometric map, slope and aspect it is possible to formulate na evolution of the geomorphological process that formed the relief. To the preparation of the DEM it is necessary to organize three basic procedures: a) contour curve's edition (AutoCAD); b) AutoCAD's data conversion into the IDRISI; c) contour curve's interpolation. The Digital Elevation Model was generated in a 30m's resolution to be compatible with the satelite's image. As a result, it was observed that the geomorphological and geological's interpretation were largely facilitaded by the DEM's use, because of a strong co-relation observed among the interpreted features in the DEM and geological and geomorphological's characteristics of the area.
