In 1952, all soil survey work by the USDA was consolidated and responsibility for Federal leadership in the National Cooperative Soil Survey partnership was given to the SCS. This included all mapping, classification, interpretation, laboratory services, map compilation and nationwide publication.
The information in a soil survey can be used by farmers and ranchers to help determine whether a particular soil type is suited for crops or livestock and what type of soil management might be required. An architect or engineer might use the engineering properties of a soil to determine whether it is suitable for a certain type of construction.
Such maps are typically richer in context and show higher spatial detail, yet are not necessarily more accurate than traditional soil maps. Soil maps produced using (geo)statistical technique can also include an estimate of the model uncertainty. [3] An example of a traditional soil map showing soil mapping units, described soil profiles and ...

The service was transferred to the Department of Agriculture on March 23, 1935, and was shortly thereafter combined with other USDA units to form the Soil Conservation Service by the Soil Conservation and Domestic Allotment Act of 1935. [6] [7] The SCS was in charge of 500 Civilian Conservation Corps camps between 1933 and 1942.
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 ...
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: Order, Suborder, Great Group, Subgroup, Family, and Series.
Pedometric mapping, or statistical soil mapping, is data-driven generation of soil property and class maps that is based on use of statistical methods. [1] [2] [3] Its main objectives are to predict values of some soil variable at unobserved locations, and to access the uncertainty of that estimate using statistical inference i.e. statistically optimal approaches.
