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 from a view of the entire Earth down to Washington DC, as first Landsat data at 15 meter resolution, then aerial photography data at 1 meter resolution appears. Animator: Steve Maher (NASA/GSFC). Scientist: Darrel Williams (NASA/GSFC). Platforms/Sensors/Data Sets: Landsat-7/ETM+.
