Farmland terrace slope detection from Pleiades digital elevation models

International audienceMediterranean 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 beneeded [1]: How to map these landscape elements from remote sensing ?
