Cadets learn from Civil War 3-D models. (Tech Talk).The U.S. Military Academy's Geospatial Information Science Program has purchased a 3-D solid terrain model of the Civil War battlefield at Gettysburg, Pa. It will be used in military history and geography courses. Computer-cartography instructors plan to present the model--built by Solid Terrain Modeling, in Fillmore, Calif.--as an example of an innovative technology to "visualize the battle-space," said John Brackhaus, the program's director. "The model was produced from a combination of 30-meter digital elevation model A digital map of the elevation of an area on the earth. The data are either collected by a private party or purchased from an organization such as the U.S. Geological Survey (USGS) that has already undertaken the exploration of the area. data, from the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. Geological Survey's National Elevation Data set, and Ikonos 4-meter multispectral imagery, from Space Imaging Inc." In military history and geography courses, the model will be employed as a visual aid for analyzing the battle of Gettysburg Noun 1. Battle of Gettysburg - a battle of the American Civil War (1863); the defeat of Robert E. Lee's invading Confederate Army was a major victory for the Union Gettysburg . The "Introduction to Remote Sensing Deriving digital models of an area on the earth. Using special cameras from airplanes or satellites, either the sun's reflections or the earth's temperature is turned into digital maps of the area. " course will use the model to discuss the integration of data collected from space-based, remote-sensing assets with other types of spatial information. Students in the "Advanced Remote Sensing" course will use the digital data to help develop "fly throughs" and virtual tours Virtual Tours The phrases panoramic tour and virtual tour are often used to describe a variety of video and photographic based media. The word panorama indicates an unbroken view, so essentially, a panorama in that respect could be either a series of photographs or panning video of the battlefield. |
