  15. Background • USGS Research Project: Information Technologies Research Project Lead • Momentum from development of GeoWall Consortium • Geo – Geology (Geography… Geometry… Geo…) • Wall – One wall of a cave – descendent of CAVElib • 3-D Viz on the cheap • GeoWall Consortium - formulation without funding • Jason Leigh University of Illinois – Chicago (UIC), Electronic Visualization Laboratory (EVL) – Cave Technology • Peter van Keken, University of Michigan - Geology • Paul Morin, U of Minnesota – Geology Visualization, Wall Evangelist • Brian Davis, EROS – Data Pimp

  16. Number of GeoWalls – 12/03 $15,000* $6,000* 2-10 new systems a week (*Cost of a modest system)

  17. Cost of a Modest System

  18. GeoWall Index (With respect to Harper’s Index, as of 12/03) Approximate number of GeoWalls:250 Number outside the US:~30 Percentage in the classroom:~75% Percentage of non-major earth science students that see a GeoWall in the US:15-25% Average cost of one “CAVE”:$1.5 million Cost of the GeoWalls currently in educational service:$1.5 million Most popular material:USGS’s Stereo LANDSAT Imagery Data transferred from GeoWall.org:279 Gigabytes Busiest day on GeoWall.org:300,000 hits in 8 hours on September 1, 2002 (Slashdot.org article) Publications beginning to appear

  19. Road Shows • National Park Service Regional HQ, Omaha • SDSM&T • Sinte Gleska University • Missouri River Institute, USD • Grand Canyon National Park • Russell Senate Office Building • 03 SD Technology Summit • Space Days, Washington Pavilion • MIB (Main Interior Building), Washington, D.C. • USGS Headquarters (x2) • ESRI User Conference, San Diego, CA • GIS Day, EPA HQ • 04 DSU CECIS Symposium • EDC Auditorium

  21. Development Direction Thus Far Hardware development • Now stable and spun off to 4 companies Software development • “Seed” applications freely distributed • Encourage the support of GeoWall software by key vendors: ESRI ArcGIS, MDL Chime, DGI EarthVision, MMK Roma, IVS Fledermaus, VRCO VGEO, AGI Satellite Tool Kit Establishment of GeoWall community • 4th Annual GeoWall Meeting Spring – May 2004 • Special interest groups being established • Museum community underway

  22. GeoWall Museum Network Alaska: The Imaginarium, Anchorage. Illinois: SciTech Hands on Museum, Aurora;Discovery Center, Rockford; Lake County Discovery Museum, Wauconda; Lakeview Museum, Peoria. Indiana: Evansville Museum of Arts and Science, Evansville; Science Central, Fort Wayne; Children’s Science and Technology Museum, Terre Haute. Iowa: Bluedorn Science Imaginarium, Waterloo. Texas: Don Harrington Discovery Center, Amarillo Other Museums: Chicago Museum of Science and Industry Adler Planetarium, Chicago Science Museum of Minnesota Lowell Observatory Texas Memorial Museum - UT Austin

  23. Final Points • GeoWall is now going beyond earth sciences • Price can’t get much lower • Basic technology is ready • Vendors are supporting the community • Critical mass has been reached in the geosciences • Assessment is just beginning • Timing for feedback is excellent • Opportunities for collaborative research
