Advancing Geoscience Education with GeoWall: A Novel Application Development Strategy

The GeoWall initiative from the University of Minnesota aims to enhance geoscience education through innovative application development strategies. By employing accessible stereo projection technology in classrooms, labs, and fieldwork, we provide interactive learning tools such as stereo maps and virtual excursions. The program focuses on creating engaging resources for students, including walking maps and high-resolution stereo imagery. Collaborating with various geoscience partners, we aim to support educators and students around the world with modern, interactive geoscience applications.

  1. The GeoWall:Application Development Strategy Paul Morin GeoWall Consortium National Center for Earth-surface Dynamics Department of Geology and Geophysics University of Minnesota 1

  2. GeoWall Stereo Projection in the classroom, office and lab Computer hardware from Best Buy Passive stereo 20+ people at a time Under $10,000 Small and Portable 2

  3. Initial Strategy Seed the community with basic applications Stereo Pairs – WallView and Viewer VRML – Immersaview Walkabout – Walking maps Identify the geoscience “Killer Vis” Earthquake hypocenters Stereo maps Stereo photography Geologic cores 3

  4. Stereo Maps Can be created from paper maps, imagery or GIS data Can be very high resolution Created using off-the-shelf software Best when using the exact same map the students use 4

  5. Stereo Pairs Natural extension to traditional field photography Two consumer digital cameras Often used for fieldtrip preparation and debriefing Easiest material to produce 5

  6. Walking a Map Examine the map from within Change the theme as you walk Maps Aerial Photography Satellite Imagery Field notes Can be used to augment fieldwork 6

  7. 3D Objects 7

  8. Topography without contours No crashing Inexpensive Will work next year Can be used in the field Anaglyph Maps 8

  9. Continuing Software Strategy Identify Earth Science apps that require vis Core interpretation 3D Mapping Seduce the key software vendor into supporting GeoWall Read: ESRI Include other key technologies IVS – topographic visualization MapServer for web based GIS delivery Use standard software to unusual applications Powerpoint for stereo photography 9

  10. CoreWall In collaboration with JOI/IODP, LacCore, LDEO, Chronos, DOSECC, EVL, SMM 10

  11. Number of GeoWalls Currently ~400 2-10 new systems a week 11

  12. How the CS Students are Trained Summer internships at geoscience departments Fieldwork AGU/GSA, etc. Sent to many geoscience workshops Publishing in geoscience journals 12

  13. Conclusions Seed example apps Collaborate with industry Take advantage of the low-end Software follows the needs of research and education GeoWall critical mass has been reached in the Geosciences 13
