                         bands (red and infrared), from distinct hydrological periods were 
                         used by PCA (Principal Component Analysis). The results obtained 
                         indicate different features of the land use changes, that were 
                         categorized on three landscape classes of the environmental 
                         status:degraded area, no-degraded and areas with regeneration 
                         process. The image processing adopted was very suitable for the 
                         goals, demonstrating the capability of the orbital data for 
                         monitoring the semi-arid landscape.",
