GNS (Geonet Names Server) The GEOnet Names Server (GNS) provides access to the National Geospatial-Intelligence Agency's (NGA) and the U.S. Board on Geographic Names' (US BGN) database of foreign geographic feature names. The database is the official repository of foreign place-name decisions approved by the US BGN. Names appear to be largely in Romanization, but there is information on the Romanization for less than a handful of languages. in Languages > General Resourceswith geographicnames
