The database is the official repository of foreign place-name decisions approved by the BGN. Geographic coordinates are approximate and are intended for general location. Place name information is based on the Geographic Names Data Base, containing official standard names approved by the United States Board on Geographic Names and maintained by the National Geospatial-Intelligence Agency. 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. To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.
