GeoWorld (04/06) Vol. 19, No. 4, P. 20; Limp, Fred
There is increasing interest in geospatial initiatives that utilize 3D data, and Fred Limp with the University of Arkansas' Center for Advanced Spatial Technologies reports that the 3D boom is being fueled by the "push" of technology and the "pull" of business reasons behind the use of the technology. The core drivers of 3D technology include basic computer system refinements, such as better memory, disks, display, and graphics performance. These are needed to support such things as stereo viewing. Another major technology push is the fast development and expanding use of LIDAR, which for many offers a quicker and more precise elevation data acquisition methodology. The 3D explosion is also being spurred by advancements beyond the traditional geospatial market, such as significant growth in the CAD 3D data generation tools and the visualization and animation software sectors. "Motion capture" is yet another key 3D technology that is driving up interest. Product lines and professions associated with 3D content are just as diverse as the content itself: Geospatial software generates and maintains geographical data; HDS and terrestrial photogrammetry document the existing world's features in detail; animation software places all inputs within a narrative framework; and motion capture inserts active humans in the resulting environment. Gaming and high-end simulation software engines possess, in addition to the above components, the capability to define visual processes based on underlying physics and object interaction.
