 ## Overview
 
-Digital Soil Mapping - The generation of geographically referenced soil databases based on quantitative relationships between spatially explicit environmental data and measurements made in the field and laboratory (McBratney et al., 2003); the spatial prediction of soil classes or properties from point data and environmental raster data using a statistical algorithm. For general information on Digital Soil Mapping, please click [here](https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/geo/?cid=stelprdb1254424).
