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.

Para a execução do trabalho foram utilizadas as bandas 2,3,4,5 e 8 do satélite Landsat8 para composição de imagens do terreno e mapeamento do NDVI, e a banda 10 para o mapeamento da TST da área de estudo. Com base nas estatísticas zonais observa-se uma correlação negativa entre os valores de NDVI e TST, ou seja, os bairros que apresentam valores altos de NDVI, em geral, mostram valores baixos de TST, e aqueles que apresentam valores baixos de NDVI, indicam altos valores de TST, o que sugere maiores concentrações de áreas com vegetação em bairros com menores valores de TST. Nesse contexto, as técnicas de processamento de imagens aplicadas aos dados de satélite podem ser utilizadas nas ações de monitoramento e planejamento ambiental urbano, detectando alterações na vegetação e mudanças na temperatura da superfície do terreno relacionadas às atividades antrópicas.EDUFU - Editora da Universidade Federal de Uberlândia2023-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/6415110.14393/RCG249264151Caminhos de Geografia; Vol. 24 No. 92 (2023): Abril; 343-355Caminhos de Geografia; Vol. 24 Núm. 92 (2023): Abril; 343-355Caminhos de Geografia; v. 24 n. 92 (2023): Abril; 343-3551678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/64151/35941Copyright (c) 2023 Joao Pedro Luiz Santos da Silva, Daniela Dantas de Menezes Ribeirohttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Joao Pedro Luiz Santos daRibeiro, Daniela Dantas de Menezes2023-04-04T17:33:14Zoai:ojs.www.seer.ufu.br:article/64151Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2023-04-04T17:33:14Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false
