Description

This item was taken from the IEEE Conference ' Rear-projecting virtual data onto physical terrain: an exercise in two senses being better than one ' This paper describes a project that combined physical model fabrication and virtual computer-based data display to create a unique visualization presentation. USGS terrain information on Prince of Wales Island, Alaska was used to create a physical prototype in SDSC's TeleManufacturing Facility. This model was then used as a mold to create a translucent plate of the terrain. Finally, deforestation data from the island was color mapped and rear-projected onto the translucent plate within a light box. The result is a very compelling display in which both the senses of sight and touch are used to make relationships between terrain features and the data more readily apparent.
