From Search Engine Watch (SearchDay):
Google has released its long-anticipated geographic search tool, a new application that combines local search with satellite images and maps from around the globe.
Google Earth is a standalone application that’s essentially an enhanced and upgraded version of its Keyhole 3D satellite imagery product. As Google has done with several of its past acquisitions, the company has also made the application free to all users, dropping its annual subscription fee for the basic version. Google Earth Plus with additional features will cost $20 per year.
I haven’t tried it yet (I’m just downloading it now) and will post my thoughts later. You can read about the software and/or download it at http://earth.google.com/
