Sistema de Informações Geográficas para gerar mapas com a localização da Sucupira (Schinopsis brasiliensis) – margem Noroeste do município de São Francisco-MG, bacia do rio São Francisco

Abstract

Managing natural resources responsibly is undoubtedly one of the biggest environmental management challenges. Thus, interpolation methods for generating Digital Elevation Models - DEM have been frequently used to help people make decisions. This study was carried out in the Northwest (B) bank of the municipality of São Francisco, North of Minas Gerais, located in the upper-middle São Francisco River basin, where the natural Cerrado suffered intense degradation in the 41 year interval (1975-2016). The aim of the project was to generate a map capable of presenting the populational average of Sucupira (Schinopsis brasiliensis) per collection point. We used overlapping cartographic images and the IDW tool of Arcgis 10.2 software. After the successful methodological experience presented in this article, results indicate that the overlapping mapping performed here shows Sucupira (Schinopsis brasiliensis) present basically throughout the studied margin, with the exception of the East and West ends. It is possible to highlight, however, a significant population growth in the South, exactly where the main water bodies of the place are, indicating that even though it is adapted to the entire study area, the species has a preference for humid regions. Further studies are suggested about the hypothesis proposed here for the distribution of the species throughout the Northwest region of the municipality of São Francisco.
