Google Maps now has a Google Earth button. Since 2008 Google Maps API developers have been able to provide a Google Earth view in their Google Maps mashups. Now it is possible to view Google Earth directly in http://maps.google.com/
This means that Google Maps users can now enjoy the 3D buildings and terrain that users of the Google Earth standalone application have long enjoyed. It is even possible to grab the embed code and place a view directly within your own website or blog.
Another great feature of Google Earth is the ability to dive beneath the ocean floor. Check out this 3D model of the German Battleship Bismark or the model of The Titanic in Google Maps.
So what are you waiting for? Go and explore some of the world's amazing buildings and landmarks directly in Google Maps:
Sydney Opera House
Statue of Liberty
Neptune Memorial Reef (Ocean)
