Where does the gssurgo soil survey data come from?
The gSSURGO Database is derived from the official Soil Survey Geographic (SSURGO) Database. SSURGO generally has the most detailed level of soil geographic data developed by the National Cooperative Soil Survey (NCSS) in accordance with NCSS mapping standards.
How are ssurgo and gssurgo datasets used?
All spatial data are stored within the geodatabase instead of externally as separate shapefiles. Both SSURGO and gSSURGO are considered products of the National Cooperative Soil Survey (NCSS) partnership. The gridded SSURGO (gSSURGO) dataset was created for use in national, regional, and statewide resource planning and analysis of soils data.
Where are soil attribute tables stored in gssurgo?
This makes it possible to offer these data in statewide or even conterminous United States (CONUS) tiles. gSSURGO contains all of the original soil attribute tables in SSURGO. All spatial data are stored within the geodatabase instead of externally as separate shapefiles.
How big is the CONUS and gssurgo database?
The state-wide databases include a 10 meter raster and the CONUS database includes a 30 meter raster. Each gSSURGO dataset includes all SSURGO vector and attribute tables (with relates) plus the map unit raster layer.
How to get gridded soil data from ssurgo?
Download gSSURGO to obtain gridded soils data for the states that have complete SSURGO coverage and do not have an RSS. SPSD created a custom set of ArcTools designed to work with gridded soils information called the “Soil Data Development Toolbox.”
Where can I get gridded soil survey data?
The conterminous U.S. and/or national collection of gSSURGO data can be obtained by contacting the USDA-NRCS National Geospatial Center of Excellence (NGCE) representative Rosemary Rivera ( [email protected]) or by phoning (817) 509-3371. The cost for this service is $250.
