Africa Soil Profiles Database, v1.1

ISRIC World Soil Information has compiled legacy soil profile data of Sub-Saharan Africa, as a project activity of the AfSIS project (Globally integrated Africa Soil Information Service), based on a wide variety of digital and analogue data sources reporting soil profile data in various formats and stamdards. The resulting Africa Soil Profiles database, version. 1.1 holds 16,711 unique soil profile records, inventoried from a wide variety of data sources (> 450), of which 15,499 records are georeferenced, including soil profile layer attribute data. Soil analytical data are available for 13,835 profiles, of which 12,683 are georeferenced. The database includes, but is not limited, to the soil attributes specified by GlobalSoilMap.net. Soil attribute values are standardized according to e-SOTER conventions and validated according to routine rules. Odd values are flagged. The degree of validation, and associated reliability of the data, varies because reference soil profile data, that are previously and thoroughly validated, are compiled together with non-reference soil profile data of lesser inherent representativeness.
