Análise Multitemporal Da Cobertura Vegetal Do Município De São José Dos Campos, Sp

Remote sensing is an essential tool for monitoring and mapping vegetation. Multitemporal analysis of satellite imagery allows for the observation of landscape evolution, fostering the development of management plans aimed at preserving natural resources and maintaining biodiversity. The objective of this article was to present a multitemporal analysis of land use and land cover in the municipality of São José dos Campos, SP, with a focus on vegetation cover, using TM-Landsat 5 and OLI-Landsat 8 images, over a period of 10 years (2010 to 2020). These images were classified into the following classes: Cerrado (savanna), Atlantic Forest, anthropogenic areas, reforestation, agricultural areas, water bodies, and urban areas, using supervised classification techniques in ArcGIS software. The results showed an increase of 4.52% in the urban area, an increase of 314.17% in the silviculture areas and consequently the reduction of the original vegetation cover of the municipality, where the areas of Cerrado were reduced by 88.9% and those of Atlantic Forest by 8.57%, evidencing the need for the implementation of projects and public policies that favor the preservation of the natural plant remnants of São José dos Campos and the protection of endemic species belonging to the present biomes in the region
