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.
