---------------------------------------- IMPORTANT NOTICE: These maps have been produced in 2015, newer versions may be available. ---------------------------------------- AfSoilGrids250m data set contains predictions of soil properties - organic carbon, pH, sand, silt and clay fractions, coarse fragments, bulk density, cation-exchange capacity, total nitrogen, exchangeable acidity, Al content, and exchangeable bases (Ca, K, Mg, Na) - for the whole African continent at 250 m spatial resolution at two / six standard soil depths. The predictions are obtained using an automated mapping framework (3D regression-kriging based on random forests). Homepage: https://isric.org/projects/soil-property-maps-africa-250-m-resolution/ Inputs: Africa Soil Profile DB, AfSIS Sentinel Site database, Africa Soil covariates (250 m), SRTM DEM and derivatives (250 m), GlobLand30 land cover data (250 m), SoilGrids1km predictions. Period (temporal coverage approximate): 1950-2012. Spatial resolution (covariates): 250 m and 1 km.
