gNATSGO data source FY2024

Gridded National Soil Survey Geographic Database (gNATSGO) gNATSGO for All Raster Soil Surveys (RSS) Web Soil Survey Gridded Soil Survey Geographic (gSSURGO) Database gNATSGO now uses the GeoPackage version of the SQLite SSURGO Template database instead of an ESRI File Geodatabase. In 2025, only a single large gNATSGO database was created for all areas of the United States and Island Jurisdictions. State tiles were not produced. This database is designed to be used with the new SSURGO Portal application Soil Data Viewer (SDV) tool, which has the same ratings as Web Soil Survey. Access SSURGO Portal at https://www.nrcs.usda.gov/resources/data-and-reports/ssurgo-portal. Refer to the Quick Start Guide for SSURGO Portal installation instructions. You can install SSURGO Portal and then use SDV to make thematic maps for the entire United States. Refer to the SSURGO Portal User Guide for SDV instructions. You can also refer to the 6 minute mark of this youtube video. https://www.youtube.com/watch?v=4FGuxqxbCG0 SDV is a replacement for the old Soil Data Viewer ArcMap tool and the old GSSURGO Create Soil Map ArcMap tool. DB Browser is a free application for viewing and querying SQLite files. GeoPackages are SQLite files and can be opened in DB Browser. Rasters of soil map units are delivered as 30m cell size tif files, with dbf attribute tables, statistics, and pyramids pre built. The source.shp file shows the original source of data, with the options being Raster Soil Survey (RSS), SSURGO, and STATSGO. The mupolygon, mupoint, muline, featpoint, featline, featdesc, and sapolygon feature classes with the database are empty but were retained due to database schema requirements.
