Soil profile databases

Soil profile in hilly province, Viet Nam

Many of the digital soil maps contain geo-referenced soil profile information for instance most Soil and Terrain database (SOTER) products do. 

Some national soil science organizations also maintain a collection of soil profile databases, although often these are not freely available. At global level ISRIC maintains the WISE soil profile database, which recently has been considerably expanded thanks to the AfSIS data set. FAO also has a considerable collection of soil profile information. These data are of utmost importance for applications in Digital Soil Mapping.
