In a scenario of urban expansion, the concern about the management of the territory considering the environmental sustainability has guided discussions in recent decades reinforcing the need for a multi-temporal analysis to understand the phenomena that involve changes in the land use and in the land cover. In this regard, several methodologies that allow to monitor the changes in the landscape have been fundamental to analyze the patterns of the organization of space. This study used orbital images of the Landsat 5-TM and 8-OLI satellites, in order to analyze the dynamics of use and ground cover in the cities of Sete Lagoas and Prudente de Morais, at the Minas Gerais State, between 1990 and 2015, to verify the spatial pattern of urban growth, since there is a conflict related to water use in the region, which has its water supply exclusively by groundwater. To this aim the quantitative comparison was made between the maps of classes of land use and land cover and the results suggest that the trend of the spatial pattern of urban growth in Sete Lagoas occurs towards the center to the northeast, southwest and southeast directions, the latter being towards the Marinheiro stream, which basin represents an important granular aquifer and its occupation by industrial activities, as signaled by the plans of urban management, is a potential environmental problem.
