Using 2023 Landsat 8 satellite images and remote sensing techniques, the EVI (Enhanced Vegetation Index) and UI (Urban Index) indices were calculated to correlate urbanization, vegetation cover, and temperature. The research found a positive correlation between urbanization and temperature rise, and a negative correlation between the vegetation index and temperature. The developed linear regression model showed a significant fit to model the LST based on the UI, suggesting that the conservation and expansion of green areas are essential to mitigate the effects of urban warming. Thus, public policies focused on green infrastructure and sustainable land use are recommended for the sustainable urban development of the region.Acesso AbertoAmazônia urbanaGeoprocessamentoGoogle Earth Engine (GEE)Urban AmazonGeoprocessingCNPQ::CIENCIAS EXATAS E DA TERRATrabalho de Curso - Graduação - ArtigoAttribution-NonCommercial-NoDerivs 3.0 Brazil
