I am trying to find a software that can find distance between two ZIP codes.
I think most of them do it by having the longtitude and latidute of each ZIP,
and substract. But this gives the air distance. Where can I find software that
find the ground distance (like in Mapquest).

Thanks,

Joe

Or, you can put in a lot of effort to rewrite MapQuest on your own.
It's not an easy task with a "trick" to it; it involves (among other
things) knowing the locations and directions of *very* large numbers of
roads.

I have not found much in the way of mapping information free. See
http://mindprod.com/jgloss/map.html for some companies who might sell
it to you.
