The 3D Geologic Map Gallery was developed by Prof. Stephen J. Reynolds, Department of Geological Sciences, Arizona State University, in some cases with the help and cooperation of other geologists. The geology was derived from scanning published geologic maps, most from the U.S. Geological Survey (USGS). Digital topography files (Digital Elevation Models - DEMs) are from the USGS and were manipulated (mostly converted to grayscale, elevation maps) using MicroDEM written by Dr. Peter Guth. MicroDEM also generated the nice contour maps. The geologic maps were then draped over digital topography using Corel Bryce4, my all-time favorite computer program. I configured Bryce4 to automatically generate 36, 72, 108, or 144 three-dimensional perspectives (bitmap images) for each map, each image being 800K to 3 Mb in size (we are talking serious megabytes here). These images were combined into a QuickTime Virtual Reality (QTVR) object movie using VR Worx. The QTVR movies on this website were derived from 800 X 600 pixel images, and mostly are between 1 and 3 Mb in size. I have larger movies created from 1600 X 1200 pixel or 1200 X 900 pixel images; these are spectacular, but are just too big for the website. These larger movies will be made available as a CD-ROM for nominal cost through Terra Chroma, Inc. (publications at terrachroma-inc.com).
This project was made possible by the NSF-funded "Hidden Earth Project", whose Principle Investigators are Stephen Reynolds, Michael Piburn, and Barbara Tewksbury.
