Google has just pushed some new imagery to Google Earth that shows much higher quality data for all of the oceans of the world. The data sadly isn’t 3D yet, but it’s certainly much better. It makes viewing the globe from high altitudes look much better. It’s not as in-depth as the rumored “Google Ocean” product, but it’s a step in that direction.
They’ve also done a bit of work on some inland bodies of water. For example, the Great Lakes are now a very interesting shade of pale blue. I assume that’s to help show their relative depth.
To see the new ocean imagery, just fire up Google Earth and there it is! Nothing new to load.
Google Earth Blog has more info and a nice before/after photo.
