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 ...
The 106 Soil Units form 26 Soil Groups. The FAO soil map was a very simple classification system with units very broad, but was the first truly international system, and most soils could be accommodated on the basis of their field descriptions. The FAO soil map was intended for mapping soils at a continental scale but not at local scale.
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 legend. In the digital era, soil maps come in various digital vector and raster formats and are used for various applications in geosciences ...
From 1971 to 1981, the Food and Agriculture Organization (FAO) and UNESCO published the Soil Map of the World, 10 volumes, scale 1 : 5 M). [2] The Legend for this map, published in 1974 under the leadership of Rudi Dudal, became the FAO soil classification. Many ideas from national soil classification systems were brought together in this ...
The original data was published in 10 volumes and 19 map sheets, from 1972 to 1977. The SVG map rendering, colour choice and layout are the work of Shyamal.

The Global Soil Partnership, [2] GSP, was initiated by the Food and Agriculture Organization (FAO) and its members with the hope to improve governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food-secure world, as well as support other essential ecosystem services.
Primary data for the soil survey are acquired by field sampling and by remote sensing. Remote sensing principally uses aerial photography, but LiDAR and other digital techniques are steadily gaining in popularity. In the past, a soil scientist would take hard-copies of aerial photography, topographic maps, and mapping keys into the field with them.
The WSM (originally known as International Soil Museum) was created in 1996 at the request of UNESCO and the International Society of Soil Science, [1] with a view to underpin the development of the FAO-UNESCO 'Soil Map of the World' FAO soil classification. The initial ISM building was located at the University of Utrecht.
