European soil database (ESDB), Dominant value rasters - version 2.0, May 2006

The European Soil Database (ESDB) contains four discrete datasets: - the Soil Geographical Database of Eurasia at scale 1:1,000,000 (SGDBE) - the Pedotransfer Rules Database (PTRDB) - the Soil Profile Analytical Database of Europa (SPADBE) - the Database of Hydraulic Properties of European Soils (HYPRES) This 1km x 1km raster version release of the database is freely available to the public and contains a 1km raster version of the vector based soil geometry (which is part of the SGDBE). Raster values have been derived using the "features to raster" tool in the Spatial Analyst extension of ArcGIS, the feature layer being a shapefile created from the SGDBE geometrical database to which attributes from SGDBE and PTRDB have been linked according to the "dominant value" principle for the "dominant value" rasters. Dominant Value principle: For each SMU (Soil Mapping Unit) and for a soil attribute P: the value of P is the class value that appears most within the SMU, i.e. each SMU is fully coloured with the colour assigned to the attribute class which is dominant within each SMU. The attributes are described at: http://eusoils.jrc.ec.europa.eu/ESDB_Archive/raster_archive/SG_attr.htm http://eusoils.jrc.ec.europa.eu/ESDB_Archive/raster_archive/pt_attr.htm This metadata record is adapted from the orginal one received from JRC.
