The problem is not the latitude/longitude. It would be trivial to compute the great circle, thus the length of the trip between A and B and divide it in smaller pieces to get 1-mile-distances. But unless you own an Aircraft & are important enough to take flights the direct route without air traffic control getting mad at you (aka: you are George W. Bush or some other bigwig goverment guy), this won't do you much good. What you needed would be a vectormap of the streets so that you could do route planning. Which is expensive to get. So I guess you are better off trying to find someone who offers that as part of the service. Diez Diez -- http://mail.python.org/mailman/listinfo/python-list
