Anthropic activities have long been changing the characteristics of the terrestrial surface and studying the dynamics of these transformations is important to implement measures that can make the environment a place favorable to living conditions. In this sense, this work evaluated by means of the methods MAXVER and METRIC / SEBAL, the changes occurred in the vegetation cover and the surface temperature in the years of 1986 and 2010, in the municipality of Santarém, in the state of Pará, and verified the significant increase of the areas of exposed soil and of the elevation of the surface temperature directly related to the suppression of vegetation and predominance of asphalt cover and verticalization of the buildings.
