The Natural Resources Conservation Service ( NRCS ) - National Cartography and Geospatial Center ( NCGC ) previously archived and distributed the Soil Survey Geographic (SSURGO) Database. Only file downloads were available from this site. This limited the amount of soil survey information that could be accessed. The NRCS - NCGC also supplied SSURGO data to the United States Department of Agriculture - Service Center Agencies (Farm Service Agency, Natural Resources Conservation Service, and Rural Development) Geospatial Data Gateway . While the Gateway provides file downloads, a customer can also order SSURGO data on CD-ROM or DVD. The NRCS Soil Survey Division recognized that increased functionality for...
We have recently added a KML export function to our online soil survey ( Soil-Web ). The Google Earth icon is displayed at map scales of 1:35000 or larger, and clicking on it will create a KML file containing the SSURGO polygons within the current viewport. The KML file contains labeled centroids, with links to the map unit descriptions which are normally found on Soil-Web. You will need a current version of Google Earth in order to take advantage of the KML produced by our website. To use this feature, zoom into a region of interest (at a scale of 1:35000 or larger) and click on the small Google Earth icon in the tool bar. If you have Google Earth installed, you may be prompted by the web browser software...
Our online soil survey can be used to access NRCS-NCSS 1:24,000 scale detailed soil survey data (SSURGO) in many parts of the lower 48 states. Where this data is not yet available, 1:250,000 scale generalized soils data (STATSGO) can be accessed instead (AZ, CA, NV only). An interactive map interface allows for panning and zooming, with highways, streets, and aerial photos to assist navigation (Figure 1). Soil polygons become visible near a scale of 1:30,000. Alternatively, a GPS point, CA Zip code, or a street address can be used to zoom in on a specific location. General usage notes and information on how our online soil survey work can be found here . Statistics on who is using our online soil survey can be...
