Digital soil mapping (DSM) in soil science, also referred to as predictive soil mapping [1] or pedometric mapping, is the computer-assisted production of digital maps of soil types and soil properties. Soil mapping, in general, involves the creation and population of spatial soil information by the use of field and laboratory observational ...
A soil family category is a group of soils within a subgroup and describes the physical and chemical properties which affect the response of soil to agricultural management and engineering applications. The principal characteristics used to differentiate soil families include texture, mineralogy, pH, permeability, structure, consistency, the ...
Mapping soils involves field work traversing the landscape and digging many holes to observe and classify the soil in various locations. Subaqueous soil mapping is performed in much the same way, except the mapper is in water. Instead of topographic maps and aerial photographs, subaqueous soil mapping uses bathymetric maps to identify ...
