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

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

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.

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. |

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?
