Geographic Name Server
Telnet 141.212.99.9 3000
Geographic Name Server, Copyright 1989, 1990 Merit Inc. All rights reserved.
>>> NEW VERSION!!! <<< Use "help" or "?" for details.
New version: Wed Mar 14 10:33:50 EST 1990
Change summary:
1) ZIP code queries now supported
2) ed(1)-style regular expression queries now supported
3) Query and session timeouts now enabled
4) Better query parsing, error messages
5) Response lines now terminated with CRLF instead of just LF
NOTE: This server is intended for use with clients which interpret
the raw protocol. However, you may also use the server directly
if you don't have the clients. There are currently four clients:
1) A user agent which pretty-prints the raw protocol and optionally
computes distance and azimuth between any two cities,
2) A filter for producing input files for Brian Reid's netmap program,
3) A US map browser which uses the X Window System,
3) A prototype X-based network browsing tool.
Data came primarily from the US Geodetic Survey and the US Postal
Service. Coverage includes all US cities, counties, and states, as well
as some US mountains, rivers, lakes, national parks, etc. A few
international cities have also been included. Unfortunately, some minor
inaccuracies remain. Merit Inc. is not responsible for maintaining this
data.
Queries should generally look like the last line of a postal address, as
in "Ann Arbor, MI 48103".
All these queries will also work:
1) ed(1)-style regular expression, like "[Bb]os.*n$"
2) A city name alone, like "Ann Arbor"
3) A ZIP or ZIP+4 code alone, like this: "46556", "48103-2112"
NOTE: only the first 5 digits in a ZIP+4 code are used.
4) As in 1) or 2) but with a state name or abbreviation, like
this: "Ann Arbor, MI", "Los Angeles, California"
5) As above but with optional nation name or abbreviation, like
"Toronto, , Canada". NOTE: there are currently very few
foreign cities.
Punctuation, white space, and upper/lower case are ignored.
Any reasonable state/nation abbreviations are recognized.
Here are more example queries:
"Ann Arbor, Mich" "48103" "annarbor,mi" "Paris,,France"
"Mammoth Cave National Park" "mount mckinley" "lake michigan"
If a query fails, try expanding abbreviations (e.g. change "Mt."
to "Mount", etc.
Interpret server replies as follows:
0 [city name]
1 [county FIPS code] [county name]
2 [state/province abbreviation] [state/province name]
3 [nation abbreviation] [nation name]
A [telephone area code]
E [elevation in feet above mean sea level]
F [feature code] [feature name]
L [latitude DD MM SS X] [longitude DDD MM SS X]
P [1980 census population]
R [remark]
T [time zone]
Z [postal ("ZIP") code]
To exit the server, enter "stop", "end", "quit", "bye",
"exit", "logout", "logoff", or control-D.
