Ain't No Mountain High Enough... - Die Google Maps API bekommt Höhenmessung.
We are therefore happy to introduce a new service to the Maps API family that enables applications to determine elevation profiles. Using either the new ElevationService Maps API v3 class or the Elevation Web Service you can request the elevation in meters for one or more sets of coordinates, or you can request a specific number of elevation samples equally spaced along a path.
