World Wind better than Google Earth?

WorldWind.jpg
NASA’s World Wind software seems to be a good competitor to Google Earth. The software has more scientific tools such as near realtime weather, the new compass, scale bar and more. Google Earth lacks the Scientific Visualization Viewer capabilities of World Wind, and cannot be extended with user-authored add-ons. VIDEO->Moreover, World Wind provides direct access to the downloaded DDS and JPEG satellite images, and the open-source nature of the program guarantees that anyone can get the source code and ‘roll their own’ version of the program.
