Geographic Name Server _A_d_d_r_e_s_s: 2145 Blaney Drive Ann Arbor, MI 48103 _E-_m_a_i_l: libert@eecs.umich.edu _P_h_o_n_e: (313) 662-6520 _D_e_s_c_r_i_p_t_i_o_n 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. _N_e_t_w_o_r_k _a_c_c_e_s_s Telnet to port 3000 on martini.eecs.umich.edu.
