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

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
