The work presented here has taken advantage from the emerging digital soil mapping technology and the 90 m resolution Shuttle Radar Topography Missions (SRTM) digital elevation model (DEM) for the development of a quantitative procedure for SOTER Terrain Unit delineation. Tha target scale were 1:1 and 1:5 million. The procedure is based on the SOTER Manual specifications and is meant to be compatible with the datasets formally developed using the traditional way. Meanwhile, suggested changes regarding the Terrein Units delineation have already been implemented.JRC.H.6-Spatial data infrastructure
