Virtual globe

NASA WorldWind, an open-source virtual globe with stars and advanced atmosphere & sunlight effects

A virtual globe is a three-dimensional (3D) software model or representation of Earth or another world. A virtual globe provides the user with the ability to freely move around in the virtual environment by changing the viewing angle and position. Compared to a conventional globe, virtual globes have the additional capability of representing many different views of the surface of Earth.[1] These views may be of geographical features, man-made features such as roads and buildings, or abstract representations of demographic quantities such as population.

On November 20, 1997, Microsoft released an offline virtual globe in the form of Encarta Virtual Globe 98, followed by Cosmi's 3D World Atlas in 1999. The first widely publicized online virtual globes were NASA WorldWind (released in mid-2004) and Google Earth (mid-2005).
