- Abstract
This paper aims to analyze the land cover modifications in the Magu River microbasin, comparing the years 2000 and 2017. The analysis drew on satellite images from Landsat 5 and 8 Orbit/Period 219/062, on August 28, 2000 and August 11, 2017. The Digital Image Processing (DIP) was performed using the SPRING software, version 5.5.3, and the mapping of the land cover classes for the abovementioned dates was carried out using the QGIS 2.18 software. Results evidenced that the study area underwent changes in land use and land coverage in the analyzed years, mainly with reduction of dense vegetation areas and increase of anthropic areas, due to the disordered urban growth and the advance of temporary agricultural practices (soybeans) affecting the local landscape.
