The Digital Earth Workbench is an interactive application that runs on a SGI Onyx Infinite Reality system and is controlled by an Immersive Workbench, tracked stereo glasses, and a tracked wand. The application allows an unprecedented freedom to roam georeferenced data sets at multiple resolutions and timescales. This animation is one of a series of direct screen captures of the application in operation. The occasional menu appearance denotes direct intervention by the operator to add or delete data or to activate a new control option. Note: Zooming down from a full view of the Earth to see topographic features in the Rocky Mountains, Alaska, South America, India, and Europe. Animator: Steve Maher (NASA/GSFC). Scientist: Steve Maher (NASA/GSFC).
