Road distance,Actual distance between two places

Question

I want to calculate the driving distance between two locations [the user\'s specified locations], before user starts the driving. I used many formulas and getDistanceFrom in

Answer 1

If you have two LatLongs you can calculate the direct distance between them; however, since you want driving directions (not as the crow flies) you'll need access to street-center-lines, so you can calculate the distance for each "leg" of the trip.

Google Maps may provide driving directions along with route distance, you'll need to check the documentation for that specific functionality.

On a second look, it appears this may not be available on the API (as of 2006), but a work-around is posted here: http://groups.google.com/group/Google-Maps-API/msg/4dc2fad4f74e3314
