		<abstract>Human interferences in the landscape through their uses have the power to change the hydrogeological system, drainage, as well as the composition and soil erosion and climate of a particular area. It is known that with the change of land use have been changes in the reflectivity of the surface and it interferes directly in the lower atmosphere the city of Uruçuí, as well as several other of Piauí, has been excelling for the increase of agricultural production, which expanded dramatically in recent years. In this application, the objective is the analysis of the surface temperature of the municipality, through images of the thermal infrared. This application is used for analysis and documentation of cases of urban heat islands, as well as extract data about climate change. Was made a temporal interval of 10 years, starting from 1985, through the years of 1995, 2005 and 2015. The data required are the thermal infrared images and the determination of this band by the satellite sensor chosen. For the production of this study, the satellites were the Landsat 5, for data between 1985 and 2005, and the Landsat 8, to data from 2015. With image processing was assessed that in a period of 30 years there has been an increase of 5 degrees Celsius in most parts of the municipality with average temperatures of 30 to 35 degrees Celsius in most of the analysed area and extensive planting areas, could be registered an increase of up to 10° c.</abstract>
