Africa Soil Profiles Database, version 1.2

ISRIC World Soil Information is compiling legacy soil profile data of Sub Saharan Africa, as a project activity of the AfSIS project (Globally integrated- Africa Soil Information Service). http://africasoils.net/services/data/soil-databases/

The Africa Soil Profiles Database version 1.2 (November 2014) holds 18,532 unique soil profile records of which 17,160 records are georeferenced, including associated soil profile layer attribute data, inventoried and compiled from a wide variety (> 500) of data sources. Soil analytical data are available for 15,564 profiles of which 14,197 are georeferenced. The database includes, but is not limited, to the soil attributes specified by GlobalSoilMap.net. The original 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. The profiles are geo-referenced with a median precision of approximately 250m. Details of the data and the data model are described in the associated report.

Earlier versions of the dataset, which is continuously updated and growing, have been posted online and are available to the project and the public. The dataset will also be made available through the World Soil Information Service. The current version is released here as version 1.2.
