The gridded National Soil Survey Geographic Database (gNATSGO) is a USDA-NRCS (Natural Resources Conservation Service) Soil & Plant Science Division (SPSD) composite ESRI file geodatabase that provides complete coverage of the best available soils information for all areas of the United States and Island Territories. It was created by combining data from the Soil Survey Geographic Database (SSURGO), State Soil Geographic Database (STATSGO2), and Raster Soil Survey Databases (RSS) into a single ESRI file geodatabase. The gNATSGO database contains a 10-meter raster of the soil map units and 70 related tables of soil properties and interpretations.
This raster dataset was generated using gNATSGO data obtained from USGS for the states of Washington, Oregon, and Idaho for use in the Washington Least Conflict Solar Project. The mapunit raster was reprojected to NAD_1983_StatePlane_Washington_South_FIPS_4602_Feet and the attribute aws0150wts was summarized for each state. The data was then clipped to the 1500m buffered WCP Study Area Boundary and a mosaic was generated.
