Google have launched “Google Maps API Premier v3,” which includes the functionality you’ve put to use in v2 plus new features that Premier partners have requested, including:
- Optimized Routing: Now you can take advantage of Google’s always up-to-date map data to find best routes. Google Maps API Premier now can optimize waypoints to give you fastest route, saving you miles, wear and tear, and fuel.
- Custom Street View Imagery: Now Maps API Premier customers can use their own imagery, whether it’s of their hotel rooms, houses for sale, or ski slopes, giving users this helpful perspective even in places beyond Google Maps Street View car or trike routes.
