Hi csg1947!

Below you will find a number of databases where you will obtain free
latitude and longitude information.


==============
Astrodienst AG
==============

Find Geographic Locations

?This database server is a reference source for private use by
astrologers, to find longitude, latitude and time zone information

Enter at least the first few letters of the name of the city to search
for (not the country). Case is not significant and accents are
ignored. You will rarely need to type the full name of a city, the
first few letters are enough in most cases.?

=============
How Far is it
=============

You can also look up longitude and latitude for many U.S. and foreign
locations using the "How Far is it?" calculator. Instead of entering
two locations, just enter the name of the city you are looking for in
the "from" box, leave the "to" box blank, and click "Look it up!" If
your city is in the database, you will get a listing of longitude and
latitude.

====================
The Global Gazetteer
====================

In my opinion this is the most comprehensive latitude and longitude database.

The Global Gazetteer has extensive lists of cities and towns for
countries around the world. Select a country or territory from the
list, and then choose the first two letters of the city or town name
you are looking for. You will get a chart of towns with longitude,
latitude and altitude.

=============
U.S. Gazetteer
=============

The U.S. Gazetteer is for U.S. cities and towns. Enter a town name or
a zipcode to find the geographical coordinates.
