Abstract
Digital soil mapping (DSM) entails the creation and population of spatial soil information systems by numerical models inferring the spatial and temporal variations of soil types and soil properties from soil observation and knowledge derived from related environmental variables. This chapter summarizes the state of the science of DSM and the mechanics of its various implementations. It has moved from research to practical application and is now widely used as a method for making soil maps. The outlook for continuing research into DSM and related efforts is positive, because objective spatio-temporal assessments of the soil resources are needed and continually require updating.
