                         images taken at different times with solar elevation angles, one 
                         in August 2000 and another in March 2001. To this end, were used 
                         bands 3, 4 and 5 of Landsat7 ETM+, obtained from Vi{\c{c}}osa, 
                         MG. First was applied the Linear Spectral Mixing Model in the 
                         original images, in order to compare the fraction-image generated 
                         component with respect to shade, where it was found that the image 
                         obtained in August (the period with lower solar elevation angle) 
                         had a higher contribution of the component's shadow to take Later 
                         in March. Subsequently, was used the topographic correction 
                         technique proposed by Smith (1980) in the original images in order 
                         to make an improvement in lighting and a reduction in the 
                         differential shading and applied the Linear Mixing Model in order 
                         to estimate the shadow component in the corrected images and 
                         compare the images generated with the-fraction-fraction images 
                         from real data from 2000 and 2001. It was found that the shadow 
                         component exerts a strong influence on images taken from different 
                         periods and that the use of Topographic Correction technique 
                         minimized the effects of shading, so the image taken in March, as 
                         that taken in August.",
