The GeoWallApplication Development Strategy

• Paul Morin
• GeoWall Consortium
• National Center for Earth-surface Dynamics
• Department of Geology and Geophysics
• University of Minnesota

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

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

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

Stereo Pairs

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

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

Anaglyph Maps

• Topography without contours
• No crashing
• Inexpensive
• Will work next year
• Can be used in the field

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

How the CS Students are Trained

• Summer internships at geoscience departments
• Fieldwork
• AGU/GSA, etc.
• Sent to many geoscience workshops
• Publishing in geoscience journals

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
