Uso do MapBiomas na caracterização da expansão urbana do município de Timon – MA

Abstract

This study uses remote sensing as a tool to analyze urban expansion in Timon - MA, addressing how this technology facilitates the monitoring of changes in land use and land cover, in a temporal space between the years 2000, 2010 and 2020. Using images of the Cerrado biome through MapBiomas, obtained via Google Earth Engine, the study applied classification and post-processing methods to map areas of forest, agriculture, urbanization, among others. The analysis identified a trend of deforestation and agricultural expansion, in addition to the growth of urban areas and the reduction of water bodies, reflecting the environmental impact of urbanization and migration to the municipality. Due to its proximity to Teresina, Timon has experienced accelerated urban growth, resulting in management challenges, such as real estate speculation, infrastructure and urban mobility. The results highlight the importance of remote sensing and geoprocessing in urban planning, assisting in decision- making and in the review of the Timon Master Plan, with a focus on land regularization and environmental preservation
