Example of the browse list: Terms that appear in italics are "non-preferred" (invalid) terms that lead to the "preferred" (valid) terms that are actual category terms. For example, if you click on canalized streams you will see that it says "Use: canals". Italicized terms are the ones that show up in the Used For lists.

The current release includes terms added from the NIMA set of categories for their gazetteer entries. In many cases, the NIMA terms are more specific than the depth of this thesaurus; therefore, a specific term like banana plantation has been related to the preferred (i.e., broader term) "agricultural sites." The latest version also contains terms added while reconverting the USGS GNIS gazetteer.
