I’ve written 2 sample applications to demonstrate how easy it is to use the API v2 of Google Maps.
I was honnestly surprised to see how easy it actually is… Have a look at the source of the pages and see for yourself 😉
The first one lets you easily get the coordinates of a spot on the earth.
The second one demonstrates how easy it is to draw a path on a map and do a simple distance computation.
Check out the Google Maps web which has tons of great examples to kickstart you !
