Description

The USGS Thesaurus is a controlled vocabulary providing category terms for scientific information products generated by the U.S. Geological Survey. It is designed as a formal thesaurus conforming to ANSI/NISO Z39.19, with rigid adherence to the hierarchical (BT, NT) term relationships, generic non-hierarchical (RT) relationships, and lead-in term relationships linking non-preferred terms to descriptors either singly (UF) or in a compound USE- WITH relationship.
