EarthBrowser is a virtual globe application I hadn’t encountered before. It’s $24 shareware and runs on Mac and Windows, but the current buzz is about the next version, version 3, which uses the Adobe Air cross-platform framework. The beta is in private testing and is not available for public download, but Digital Geography has a preview. Noel writes that it “in a number of respects will be a genuine alternative to Google Earth, indeed possibly a better classroom tool for studying certain topics, especially weather and tectonics.” Via Digital Earth Blog and Slashgeo.
