Overview:

The Geographic Names Information System (GNIS) contains name and locative information for almost 2 million physical and cultural features located throughout the United States and its Territories. GNIS was developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names (BGN) to promote the standardization of feature names. GNIS is being compiled in phases. The first phase is complete for the entire U.S., and entailed the collection of names from Federal sources including large-scale USGS topographic maps, Office of Coast Survey charts, U.S. Forest Service maps, and digital datasets distributed by the Federal Communications Commission, the Federal Aviation Administration, and the U.S. Army Corps of Engineers. The second phase of data collection is complete or in progress for about 90% of the U.S., and captures names from State, locally, and other published current and historical maps, charts, and texts.

Standard-Format Digital Extracts:

The USGS distributes standard-format digital extracts from GNIS that contain information about features in each State and Territory. Four topical extracts are also available:  the Populated Places file lists information about all cities, towns, housing subdivisions, and neighborhoods throughout the U.S. that are described in the database, the U.S. Concise file lists information about large physical and cultural features, the Historical Features File includes entries for features that no longer exist, and the Antarctica file contains entries throughout the continent of Antarctica as approved for use by the United States Government.

A single asterisk (*) following the name of a State or Territory file indicates there has been no Phase II data compilation for that file. Two asterisks (**) following the name of a State or Territory file indicates Phase II data compilation is in progress for that file.  Phase II updates are applied to the database daily, however the downloadable extract files are only replaced periodically as Phase II updates are applied.

Downloadable Extract Files:

The available files are summarized as follows:
