Description: This work proposes a methodology for sugarcane expansion monitoring and its possible impacts in the regional hydric dynamic through the real evapotranspiration estimation (ET) based on Terra/Modis satellite data. The methodological approach is based on a systematic and automatic land use mapping that uses a sequence of temporal profiles Vegetation Index (NDVI) built with Modis data JONATHAN (2005). Previous Studies (MEIRELLES et al, 2006 JONATHAN et al 2008); as well as some preliminaries results developed on the scope of this work, shown the applicability of the proposed method as a tool for regional monitoring land use dynamic and its impacts. The real evapotranspiration is calculated through SEBAL algorithm (Surface Energy Balance for Land) developed by BASTIAANSSEN (1995) for energy balance estimation. The study area is the southern portion of Goias state in Brazil, where the sugar cane expansion has being increasing drastically in the last decades.
