agency bullet NGA GEOnet Names Server (GNS)

The geographic names in this database are provided for the guidance of and use by the Federal Government and for the information of the general public. The names, variants and associated data may not reflect the views of the United States Government on the sovereignty over geographic features.


From approximately June 14th to 16th (subject to change), the legacy GNS will be decommissioned and replaced with the new Geographic Names Server, as part of NGA’s Foundation GEOINT Modernization program. During the crossover in systems, there will be a mandatory outage lasting approximately 3 days. During that time, users can reach out to (SBU) for any data needs they have. Information on the new data schema is below.

Putting a Name to a Place

       The GEOnet Names Server (GNS) is the official repository of standard spellings of all foreign geographic names, sanctioned by the United States Board on Geographic Names (US BGN). The database also contains variant spellings (cross-references), which are useful for finding purposes, as well as non-Roman script spellings of many of these names. All the geographic features in the database contain information about location, administrative division, and quality. The database can be used for a variety of purposes, including establishing official spellings of foreign place names, cartography, GIS, GEOINT, and finding places.
