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.

The environmental resilience is strictly dependent of water availability. The identification of priority areas is important to conservation aid land-use planning and urban expansion, conservation, and policy strategy. The goal was to identify priority areas aiming water provision and environmental conservation at the "Canal do Rio Guandu" watershed in Rio de Janeiro, Brazil. To address the goal four micro-basins included in the watershed were selected to optimize collect field data and create the criteria to define the priority levels. Based on prior literature, legacy and field data, an assessment method was proposed based on map algebra with support of Geographical Information System, gathering professional tacit knowledge with spatial data to support the selection of strategic areas. The approach based on was successful to select primarily priority areas and can contribute to regulate the local policies, pointing out areas that can connect legally protected areas with forested fragments, which presents great importance to urban and rural supply. |
