Map Routing, a la Google Maps?

Question

I\'ve always been intrigued by Map Routing, but I\'ve never found any good introductory (or even advanced!) level tutorials on it. Does anybody have any pointers, hints, etc?

Answer 1

Instead of learning APIs to each map service provider ( like Gmaps, Ymaps api) Its good to learn Mapstraction

"Mapstraction is a library that provides a common API for various javascript mapping APIs"

I would suggest you go to the URL and learn a general API. There is good amount of How-Tos too.
