The Soil Survey Geographic Database (SSURGO) data set represents soil map units and related tabular data. This is the most detailed soils data available from the Natural Resource Conservation Service located within the United States Department of Agriculture.
Soil map units are the basic geographic unit that tabular soils data are tied to. The tabular data is made up of many related tables. MapWise utilizes a subset of the SSURGO data set that was generated by FGDL. This version of soils data is a simplified view of tabular soils data designed to make it easy to visualize and reference basic soils information. MapWise also obtained additional soils tables from the SSURGO database for calculation and presentation of information such as crop yields by crop type.
Soil scientists across the country have spent decades developing detailed soils maps and associated data. Before the digitization of soils data, NRCS collected soil data on paper and published soil books by county. These books contained detailed soil maps overlaied on aerial photos, discussions of soils present within the county, and many tables of information that all tied back to the map units represented on the maps. All of this information was digitized in the 1990s and 2000s for use within Geographic Information Systems (GIS).
Soil properties play a large role in the suitability of land for various purposes. Soils data are widely used for evaluating and managing land involved in agriculture, industry, urban development, and recreation.
