Influência da Infraestrutura de Transportes sobre a Temperatura de Superfície em um corredor BRT, na cidade de Goiânia/GO.

The artificialization in urban areas has contributed to the concentration of several environmental problems, among which is the change in urban microclimate, including surface temperature. Thus, this research aims to analyze the impacts of the construction of a Bus Rapid Transit System (BRT), which is located in the city of Goiânia, on surface temperature, before and after its implementation. The methodology involved the analysis of orbital remote sensing images from the Landsat 8 satellite, OLI, and TIRS sensors, manipulated in a Geographic Information System (GIS). For that purpose, it was necessary to calculate the brightness temperature; emissivity correction, and; surface temperature calculation. The results have revealed the alteration of the urban landscape influenced by the transportation corridor, the main ones being in the land surface temperature (SST), with the intensification of high temperatures in areas where there was an increase of paved and commercial surfaces and reduction of the temperature where arborization managements were employed.
