Urban evolution becomes a space-transforming agent capable of changing Normalised Difference Vegetation Index(NDVI)and Land Surface Temperature(LST)emissivity reflectance on the land surface.Therefore,this study identifies NDVI and LST variations locally,but it can also be applied in other cities on a global scale.In general,it aims to analyse NDVI and LST on surface areas of avenues and urban streets of Sector 1,located in downtown Passo Fundo,in the southern region of Brazil,from 2013 to 2020.Methodologically,treated Landsat 8 satellite images were used to obtain NDVI and LST variations in this study.Subsequently,data of 80 points in the avenues and streets of Sector 1 were collected over a distance of 100 meters spaced from each point.These data were statistically analysed concerning the dispersion of NDVI and LST from 2013 to 2020.The results revealed a strong interaction between NDVI and LST,demonstrating the need to conserve urban vegetation to improve temperature,which positively favours urban ambience indexes. 展开更多
