Abstract: MAP SERVICE INFORMATION: The Prime Farmland map service originates from the NC Department of Agriculture and Consumer Services, Emergency Programs Division. It can be accessed by using this URL in an Esri client: https://www.ncmhtd.com/arcgis/services/NRCS/NRCS_SoilData. The REST service URL is: https://www.ncmhtd.com/arcgis/rest/services/NRCS/NRCS_SoilData/MapServer. DATA DOWNLOAD INFORMATION: SSURGO soils can be downloaded from the NRCS Soil DataMart website at http://SoilDataMart.nrcs.usda.gov. This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.
Purpose: SSURGO depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey.
Supplemental Information: Digital versions of hydrography, cultural features, and other associated layers that are not part of the SSURGO data set may be available from the primary organization listed in the Point of Contact.
