ALTERAÇÕES ESPAÇO-TEMPORAIS DE USO E OCUPAÇÃO DO SOLO NAS MARGENS DE RODOVIAS: UM ESTUDO DE CASO PARA TRECHO KM100-135 DA SC-283 EM SANTA CATARINA

Abstract

The advancement of human activities and urban expansion along highways have caused significant changes in land use and coverage. This study aimed to analyze the spatial changes that occurred in 2005, 2015, and 2025 along the 35 km stretch of state highway SC-283, in Santa Catarina, using aerial images and remote sensing and geoprocessing techniques. The images were georeferenced, classified using semi-automatic and manual methods in the QGIS software, and organized into different influence bands. The results revealed a significant expansion of human use, especially near urban crossings and mining areas, in addition to the conversion of forest areas into crops and exposed soil. Siltation in water bodies and irregular occupations in legally protected areas were also observed. The research reinforces the importance of multitemporal monitoring for territorial management, highlighting the need for public policies that combine urban development with environmental conservation.
