                         between the texture of LANDSAT images and topographic variation. 
                         This study was carried out on three test sites because they showed 
                         similar topography and ground cover. Topographic data were 
                         collected from LANDSAT images and topographic maps. A roughness 
                         index was used to represent image texture. This index is the tonal 
                         variation within a 0,5 x 0,5 cm grid. Declivity data were 
                         collected from topographic maps at different scales to correlate 
                         with the roughness index. The obtained results showed the 
                         possibility of characterizing topographic conditions by analyzing 
                         the texture of LANDSAT images.",
