This study presents soil property estimates for the world for application at a broad scale. The GIS dataset was compiled using traditional mapping approaches. It is comprised of a soil -geographical and a soil attribute component. The former was derived from a GIS overlay of the Harmonised World Soil Database (HWSD) and Köppen-Geiger climate class map as a co-variate, while soil property estimates attribute data for these compound map units were derived using taxotransfer (TTR) procedures. The TTR scheme draws heavily on statistical analyses of analytical data managed in the ISRIC-WISE soil profile database.
