TerraFly: Virtually Fly Over the Entire United States

TerraFly is an interactive tool that allows for visualization and manipulation of spatial data. Accessed via a standard Web browser or customized CD-ROM versions, and independent of a users' level of expertise, this system allows the integration of remotely sensed data with digital data while a user is seamlessly flying over and viewing the resulting imagery. Data currently available includes land, urban, and coastal imagery collected by satellites, aerial photography, and other remote sensing means covering 97% of continental US (including Alaska) in high quality. Features that expand the data manipulation capabilities in TerraFly include: a compass control that allows 360-degree control of flight direction and speed, access to a database of place/street names and their coordinates, complete descriptions of areas of defined interest, zoom in/zoom out capabilities, ability to view specific spectral bands of the imagery, and information overlays that allow users to highlight specific features from the database. TerraFly supports synchronous flight in multiple windows, so imagery taken at different times, with different resolutions or camera-types can easily be compared...
