Mediterranean farmers have adopted from Roman timesoil conservation practices. By decreasing slope intensities and lengths, terraces are one these soil conservation practices. The spatial pattern of terrace slopes is hetero- geneous and depends on natural terrain slope. In erosion and hydrological studies, maps of terraces slopes may be needed [1]:  How to map these landscape elements from remote sensing ?  Is a Pleiades derivated DEM suitable and accurateenough to map these landscape elements ?
