The Soil and Terrain digital database (SOTER) stores attribute data on landform and soils, the United Nations Environmental Program (UNEP) create a soil and terrain digital database with a global coverage at a spatial resolution of one kilometer approximately. For a little country as Lebanon such data with a very low resolution cannot be useful, Until recently, only manual methods were used to delineate SOTER (SOil and TERrain Digital Database) Units [21]. Theaimofourstudyisto apply aquantitativemethodtoderive terrain classes that match the physiography SOTER of the Lebanese territory at regional scale. According to SRTMdigital elevation model todefinetheSOTERTerrainUnit: hypsometry, slope, reliefintensity and stream density. Several GIS techniques were employed to translate the SOTER mapping concept. The four features are combined and vectorized to achieve the delineation of the SOTER Terrain unit’s map at a spatial precision of 90 meters.
