Soil Data Access Web Service

posted on 2024-02-15, 17:12 authored by Natural Resources Conservation Service

Soil Data Access is the name of a suite of web services and applications whose purpose is to meet requirements for requesting and delivering soil survey spatial and tabular data that are not met by the Web Soil Survey and Geospatial Data Gateway websites.

The current Soil Data Access Web Map Service (WMS) supports Open Geospatial Consortium (OGC) WMS version 1.1.1 requests while the current Soil Data Access Web Feature Services (WFS) support OGC WFS version 1.1.0 (GML2/GML3) requests. GML is an acronym for Geography Markup Language, and is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. EPSG is an acronym used throughout the Soil Data Access web pages. It stands for European Petroleum Survey Group. They publish a database of coordinate system information plus some very good related documents on map projections and datums.

Intended use

The USDA-NRCS Soil Data Access website allows you to: Request data for an ad hoc area of interest of any size. Obtain data in real-time. Request selected tabular attributes. Obtain tabular data where the organization of that data doesn’t have to mirror that of the underlying source database. Obtain data bundled by request, rather than by survey area.
