| Resumo: | This article aims to carry out a comparative analysis between the vegetation cover, given by the Normalized Difference Vegetation Index (NDVI), and the Terrestrial Surface Temperature (TST) of the urban area of the municipality of Arapiraca, Alagoas, using the zonal statistics extracted of the districts. In order to execute of the research, bands 2,3,4,5 and 8 of the Landsat8 satellite were used to compose terrain images and NDVI mapping, and band 10 to map the TST of the study area. Based on the zonal statistics, a negative correlation is observed between the values of NDVI and TST, the districts that present high values of NDVI, in general, show low values of TST, and those that present low values of NDVI, indicate high TST values, which suggests higher concentrations of areas with vegetation in the districts with lower TST values. In this context, image processing techniques applied to satellite data can be used in monitoring and urban environmental planning actions, detecting changes in vegetation and changes in the temperature of the land related to anthropic activities surface. |
