             abstract = "The objective of this study is to apply a simple method to 
                         estimate the actual evapotranspiration at Rio Pirapama 
                         basin(Pernambuco State, Brazil), through estimates of reference 
                         evapotranspiration and vegetation cover fraction, using images 
                         from the MODIS / TERRA sensor (MOD13Q1 product NDVI). The 
                         estimation method of actual evapotranspiration through GIS 
                         techniques and satellite images makes use of the rate between 
                         reference evapotranspiration values and the vegetation cover 
                         fraction. To estimate the reference evapotranspiration (ETo), the 
                         methods of Penman-Monteith-FAO, Hargreaves, Camargo, Thornthwaite 
                         and Makkink were used, based on daily weather data from three 
                         automatic stations from INMET (Brazilian National Meteorological 
                         Institute), located around studied basins area. The results showed 
                         that the direct observation for the days analyzed allowed to note 
                         that the spatial distribution of the results of ETr (actual 
                         evapotranspiration) is the same, since the maps had the same 
                         origin (the map of vegetation cover fraction), differentiating at 
                         reference evapotranspiration values used for estimate of actual 
                         evapotranspiration. It is noted that the Makkinks method presented 
                         an upper limit of evapotranspiration than that estimated by the 
                         method of Camargo. This is because the estimation of the reference 
                         evapotranspiration was higher by Makkink method than Camargos.",
