Google has released an API for plotting routes on maps

Google has released Directions API , an API that provides tools for plotting routes on Google Maps that you can use on your sites. Here is a list of API features:

• You can request a route between two points, or a sequence of points.
• You can request results in various languages.
• You can customize the answers for your application by choosing between displaying the route as text or as a broken line on a map.
• The API works on maps of the USA, Canada, France, Germany, Italy, Spain and Australia.

Unfortunately, you cannot make a route from New York to Paris, but no one bothers to make an offer to “sail across the Atlantic Ocean”.

Now there is a limit of 10 thousand requests per day per API key, but after a while the number of requests will be increased.
