The GeoWall:Application Development Strategy

1

GeoWallStereo 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

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

4

Stereo Pairs

Natural extension to traditional field photography

Two consumer digital cameras

Often used for fieldtrip preparation and debriefing

Easiest material to produce

5

Walking a Map

Examine the map from withinChange the theme as you walk

MapsAerial PhotographySatellite ImageryField notes

Can be used to augment fieldwork

6

3D Objects

7

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

2-10 new systems a week

Currently ~400

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

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
