Way to get an array of latitude/longitude points (tuples) from a trip

[kbperry]

I am not sure if this is the right place for this, but I thought it was
worth a shot.

What I want:
Enter a From: street address and a To: street address, and then specify

an interval (say every half mile). Then, I click a submit button, and
it gives me latitude and longitude points (in order) from the beginning

of my trip to the end of my trip in 1/2 mile increments.
I can't seem to find anything to simulate this, and I am not sure how
to go about coding this either.
BTW - I have used Yahoo geocoding service (to my delight), and while it

is a good service, I don't see a way to do this unless we knew every
street address in 1/2 mile increments.

Are there any Python modules that would assist with dealing with
latitude and longitude?
Can anyone out there help?

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.

Yeah, I am starting to wish we drove in straight lines.

It just seems odd with all of the map software out there, that this
isn't available.

I wonder how expensive that would be....probably way out of our price
range.
