This CD-ROM contains the Digital Soil Map of the World in various formats, verctor as well as raster, supported by most GIS software. The base material is the FAO/UNESCO Soil Map of the World at an original scale of 1:5 million. Programs and data files give tabular country information on soil characteristics and derived soil properties from the map are included, such as pH, organic carbon content and soil moisture storage capability. In addition programs and data files are included that display derived soil properties. The revision included the adding of a number of user-friendly ArcView files allowing the display of dominant soils by continent and the inclusion of the update of the image of the WRB World Soil Resources Map.
