MAPPING LAND USE IN THE MUNICIPALITY OF ÁGUA BRANCA-PI

Abstract

The application of remote sensing to produce maps is an important methodology for the observation of different types of land use, such as urbanized areas, areas with different types of vegetation, water bodies, pastures, fires and other uses. The analyses related to land use consist mainly in knowing how the areas of interest are being used, thus allowing a better definition of anthropic interactions with space, constituted by a spatial representation of such interactions. The present research aimed to map and evaluate the different land uses in the municipality of Água Branca/PI, which is located in the microregion of Médio Parnaíba Piauiense. For the mapping, Geographic Information Systems (GIS) tools were used, using the QGIS 3.22 software, LANSAT 8 satellite images, OLI sensor and information from the IBGE database. The results showed that the most present uses in the municipality are urban areas (37.51%), shrub vegetation (26.78%), tree vegetation (22.95%), pastures (10.84%), fires (1.69%), water bodies (0.23%). Therefore, it was verified that the applied analyses imply in a tool to help decision making, considering that there is a great contribution of the research in what concerns the territorial and environmental planning of the municipality.
