Initial Strategy
Seed the community with basic applicationsStereo Pairs – WallView and Viewer
VRML – Immersaview
Walkabout – Walking maps
Identify the geoscience “Killer Vis”Earthquake hypocenters
Stereo maps
Stereo photography
Geologic cores3

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 withinChange the theme as you walk
MapsAerial PhotographySatellite ImageryField notes
Can be used to augment fieldwork

Anaglyph Maps
Topography without contours
No crashing
Inexpensive
Will work next year
Can be used in the field8

Continuing Software StrategyIdentify Earth Science apps that require vis
Core interpretation3D Mapping
Seduce the key software vendor into supporting GeoWallRead: ESRI
Include other key technologies IVS – topographic visualizationMapServer for web based GIS delivery
Use standard software to unusual applicationsPowerpoint for stereo photography

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
