gNATSGO (gridded National Soil Survey Geographic Database)¶
The gNATSGO (gridded National Soil Survey Geographic Database) database is a composite database that provides complete coverage of the best available soils information for all areas of the United States and Island Territories. This collection is sourced for the raster data only. Since the original format of the data is proprietary the source COGs are sourced from Planetary Computer STAC catalog.
The gNATSGO database was created by combining data from three sources: the Soil Survey Geographic Database (SSURGO), State Soil Geographic Database (STATSGO2), and Raster Soil Survey Databases (RSS). SSURGO is a USDA-NRCS Soil & Plant Science Division (SPSD) flagship soils database that has over 100 years of field-validated detailed soil mapping data. SSURGO contains soils information for more than 90 percent of the United States and island territories, but unmapped land remains.
STATSGO2 is a general soil map that has soils data for all of the United States and island territories, but the data is not as detailed as the SSURGO data. The Raster Soil Surveys (RSSs) are next-generation soil survey databases developed using advanced digital soil mapping methods. The gNATSGO database is composed primarily of SSURGO data, with STATSGO2 data used to fill in the gaps. The RSSs were merged into the gNATSGO after combining the SSURGO and STATSGO2 data. The extent of RSS is relatively limited at this time but is expected to increase in the coming years. To use the map unit values contained in the mukey raster asset, you will need to join to tables represented as Items in the gNATSGO Tables Collection. Many items have commonly used values encoded in additional raster assets.
