The National Geospatial-Intelligence Agency is conducting very important maintenance on the GEOnet Names Server (GNS) website resulting in limited availability to our products during Memorial Day weekend.
All website functionality should be available by 2300EST on 29 May 2016 when full service is restored. NGA and GNS are sorry for any inconvenience during this maintenance period.
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.
This page provides access to an OGC compliant Web Map Services (WMS) interface and high level
graphical search. This page will function properly with most modern browsers.
This page provides access to a text-based interface and mechanisms for initiating
queries and generating outputs. It also provides access to lookup (domain) tables
for listing and a description of values such as primary administrative division codes
and names, geopolitical entity codes and names, feature designation (feature type)
codes and names, etc. This page will function properly with most modern browsers.
