ISRIC Soil Information System (ISIS) brings the ISRIC World Soil Reference Collection on-line and characterizes a collection of monoliths with morphological, analytical data (chemical and physical) that represent the main soil groups of the World. ISIS holds data on the World Soil Reference Collection including over 950 monoliths from over 74 countries with detailed soil profile and environmental data. The collection provides a scientific reference for the legend of the FAO_UNESCO Soil Map of the World and internation soil classification system that evolved from it, the World Reference Base for Soil Resources (WRB) and other international systems (USDA Soil Taxonomy).

Users currently have access to site data (60 attributes on location, geology, landform, soil surface properties, hydrology, land-use, vegetation and climate) and soil data (soil profile description according to the FAO Guidelines; 100 physical, chemical and mineralogical attributes; and attributes for classification in the FAO-Unesco Legend (1974), the Revised FAO-Unesco Legend (1988), World Reference Base for Soil Resources (all versions), USDA Soil Taxonomy, and a national classification system, as available). ISRIC will continue to enlarge its soil reference collection.
