 ### Identification (Taxon Names)
 Identifications in Arctos can be made in [several formats](https://arctos.database.museum/info/ctDocumentation.cfm?table=cttaxa_formula), however, they all must include a reference to at least one term from the [Taxon Name Table](https://arctos.database.museum/taxonomy.cfm). This table is maintained by Arctos Operators with manage_taxonomy permissions and is not guaranteed to exclude misspellings or errors, but when these are discovered, there are paths for linking poorly formatted names to the correct version and/or quaratining such names from use while still allowing them to be present for the purposes of search and discoverability.

 ## Data Quality Checks
 
 ### Agents
 1. Agent pages include a list of potential duplicates.
 
+### Locality
 
+Higher geography in Arctos is a controlled vocabulary of data objects associated with spatial polygons. Components are extracted on demand, never stored. Assigned coordinates plus error that do not fall within the higher geography polygon for any location generate a data quality report for all collections using the locality. This clearly highlights improper negation as well as coordinate/geography mismatches.

+### Taxonomy
+
+Tools in Arctos allow for review of taxonomic classifications with missing terms (Family, Order, etc.) of to find taxon names with no associated local classification. Arctos also pulls data from GlobalNames so records are generally still discoverable even when local taxonomic sources are missing terms or entire classifications.
