There's a new version of Google Earth available today.
New Google Earth 4 features:
- 3D Models - GE 4 supports a new format which allows for models which have textures. It also supports the new 3D buildings layer. The official release of GE includes lots of optimizations to improve 3D viewing.
- Time Animation - the new time slider appears when KML content has been stamped with time.
- New Look - GE 4 has a much cleaner look than GE 3. It devotes more attention to the main 3D view, and has a new navigation gadget which appears in the upper right corner. There are too many enhancements to list them all. Some notable ones are: Support for radio buttons in KML, network link icons animate when loading, new organized menus, and more GE Options.
- Controllers - Support for joystick controllers and flight simulator yokes. And, best of all, the new SpaceNavigator (Windows only at the moment, but a Mac driver soon).
- Regions - GE 4 supports very large image overlays which can be "tiled" or "regionated" so you can view the full detail as you zoom in.
