As found on the SearchEngineWatch web site:
With all of the interest in satellite and aerial images these days I thought TerraFly, a service from Florida Int. University (with support from IBM), was worthy of another mention on the blog. Terrafly not only offers interactive satellite/aerial images but also provides local info for most of these images. It’s very easy to try the service.
It seems a lot more technical, and has a lot more information available to the user. I had a hard time pulling up a picture of Niagara Falls, but got all sorts of information about streets, facilities, and other things around Niagara Falls.
