Google said that it has opened to third-party developers the programming interfaces to Google Earth, the company’s 3-D visualization software. That will allow developers to embed Google Earth on their Web sites, much like they already can do with Google Maps.
Google Earth can now be used from a browser, without having to install the full application. Instead of the application, you need to install a plug-in that only works in Firefox and Internet Explorer 6/7 on Windows.
