The efficient management, discovery and retrieval of geospatial information are supported by indexing thematic content, geographic location and data extent. The FGDC Content Standard for Geospatial Metadata requires that data providers use theme, place, stratum, and temporal keyword indexing derived from an associated thesaurus.
The lists on this page are keywords, some Oregon specific, that may be used and cited for metadata.
