Geoprocessamento aplicado á gestão dos recursos naturais da Bacia Hidrográfica do Baixo Rio Grande - GD 8, no cerrado mineiro

Abstract

Anthropic action is often responsible for the degradation of natural resources, causing damages to plant cover, rivers and their springs, as well as key areas for biodiversity. Nowadays, many Geoprocessing resources can be used for the preservation and planning of natural areas. Biomes and hydrographic basin are on the list of study areas where these tools can have a great positive impact. Therefore, the aim of this study was to develop and provide maps that can contribute for the understanding of how they are distributed and how the natural resources can be managed in the region of the Rio Grande hydrographic basin, in Minas Gerais, which is in the Cerrado area. For the production of maps, images, remote sensors, other environmental data of interest (water quality, water courses, hydrographic basins, altimetry, etc) available on the ANA (National Water Agency), IGAM (Institute for Water Management of Minas Gerais), INPE (National Institute for Space Research) website and software features (e.g. ArcGIS) was used. The technologies for obtaining, storing, processing and presenting georeferenced data, refer to hypsometry, land slope, vegetation cover and land use, water quality, among others, was applied. The results show that the generated cartographic products are able to fulfill the specified proposal of this work. Also, that can be used to a more depth view of human actions effects that have brought to the natural environment, as well as subsidize environmental planning in the studied region.
