Enterprise Web Thesaurus

The USGS Enterprise Web Thesaurus is a tool to provide better access to U.S. Geological Survey science information. This database gives a controlled list of subject terms used for tagging USGS information resources to allow searching from a formal index.

The thesaurus is limited in depth and specificity of coverage. It does not attempt to replicate existing controlled vocabularies, such as GeoRef. The intention is to provide a set of controlled vocabulary terms to be used as an additional searching tool along with free-text searching, framework organizations, and the use of other terminologies, taxonomies, and categories.

  • Basic Concepts [PDF Format, 163 Kb] - Provides an overview of the Thesaurus with a description of the basic design concepts, organization and indexing.

  • Thesaurus (Hierarchical) [PDF Format, 239 Kb] - Shows the structural hierarchy of terms selected in the thesaurus.

  • Thesaurus (Alphabetical) [PDF Format, 1,496 Kb] - This is an alphabetical listing of terms with definitions, and see references.
