Arizona Geophysics 3D was developed by Stephen J. Reynolds, Joshua A. Coyan, and Julia K. Johnson, Department of Geological Sciences, Arizona State University. The QuickTime movies were constructed by draping the geophysical maps of Arizona over digital topography using the Corel program Bryce5. The maps are shown with 4-times vertical exaggeration. We set up Bryce5 to generate thirty-six 3D perspectives for each 1° X 1° quadrangle, and these were combined into a QuickTime VR object movie using VR Worx.
Source maps are from Lysonski and others (1980; residual Bouguer gravity), Sauck and Sumner (1970; aeromagnetics), Oppenheimer and Sumner (1980; depth to bedrock), and Richard and others (2000; geology). Paper copies of these maps can be purchased from the Arizona Geological Survey. Digital topography files (Digital Elevation Models - DEMs) are from the U.S. Geological Survey. The shaded relief map is from Ray Sterner of Johns Hopkins University.
