Here is shown a multidisciplinary approach for geomorphological analysis using remote sensing data. An image processing method based on principal component analysis and high pass convolution filter, has been applied to Landsat Thematic Mapper MS satellite date to produce an image map where the spectral and spatial infoprmation of different surface units have been enhanced. Differnt morphogenetic processes have been distinguished; morainic deposits results clearly discernible from the "in situ" material.
