            As part of a network mapping project, we have implemented  a
            TCP-based  geographic  name  server.  In response to queries
            consisting of a city name and/or ZIP code  and  an  optional
            state  and/or  country  abbreviation, the server retrieves a
            variety of data from a database  containing  information  on
            all  US  cities  (~150,000).  Queries containing UNIX ed(1)-
            style regular expressions are also supported.

            The geographic names database contains state, county,  lati-
            tude and longitude for all US cities.  It also contains 1980
            census population, elevation, area code, and ZIP code for  a
            large  subset  of  the  cities, as well as a small number of
            international cities.   The  database  contains  information
            about  other  geographic  features such as counties, states,
            rivers,  lakes,  summits,  etc.  in  addition  to  populated
            places.

            The raw data were obtained from the United  States  Geodetic
            Survey (USGS) and the US Postal Service.  USGS is developing
            a Geographic Names Information System  (GNIS)  as  the  main
            repository for its ongoing National Gazetteer project.

            friendly (it is designed for use by programs).
