Good quality spatial information about the soil at the appropriate scale is a necessary requirement for understanding soil functioning, its quality and value. DSM provides this information.
Soils are by nature heterogeneous and consequently obtaining exhaustive spatial information on soil properties is resource and time consuming. There is also an enormous amount of legacy and existing soil information that is semi-quantitative or qualitative rather than strictly quantitative. Digital Soil Mapping is the nexus where existing and new environmental data are combined with quantitative landscape models to supply much needed spatial information on soil properties. Our interest is in the development and use of mathematical and statistical models to generate predictions on soil properties. These mathematical models are then used to predict soil properties at unsampled locations with uncertainty at local, regional, national and global scales. Integrating this information into soil process or functional models results in a digital assessment of land capability.
