Day 1 Tuesday 1 March 2005

8:00 Continental Breakfast at the Synthesis Center

8:30 Introduction and logistics (Meertens and Banton)

8:40 Introduction to GEON science problems and visualization requirements and workshop goals, Chuck Meertens, UNAVCO

9:00  Session 1: Science Visualization Needs – The science “Domain” view (Session Chair Arrowsmith) GEON Science:

Keynote Talk: Visualization paradigms and their possible roles in GEON
Mark Gahegan, GeoVISTA Center, Geography Department, Penn State University

9:30 GEON Science PI talks. A series of 15 minute talks (plus 5 minutes for questions) that touch on the following topics:

  • Visualization software that scientists are currently using
  • Data requirements
  • Special visualization needs
  • Model visualization, interactive computation, comparison with data
  • Integration requirements for the GeonGrid
  • Difficulties using software
  • Questions and Answers after each talk


Ramon Arrowsmith, Department of Geological Sciences, Arizona State University

Randy Keller, Dept of Geological Sciences, University of Texas at El Paso

Luisa Marie Crawford, Geology Department, Bryn Maar


10:30 Break


Krishna Sinha, Geology Department, Virginia Tech

John Oldow, Department of Geological Sciences, Univeristy of Idaho

Dogan Seber, San Diego SuperComputing Center

11:45 Demonstration advertisements (1-2 minutes each)


12:00 Lunch


1:00 Wrap up of morning session. Summary of common needs and themes from session chairs.

1:15 - 3:15 Two back-to-back software demo sessions. Half of the demonstrations will take place the first hour and half the second hour to allow developers to see each other's visualization tools. The Synthesis Center has a sterographic wall (running on its own Windows XP computer) and four 42 inch LCD displays set up around the Center, that can connected to demonstrators own laptops.


3:15 Break


3:30- 5:00 Breakout Groups. Two groups will be formed to discuss:

  • Visualization 2D, 3D, 4D
  • Data needs, data interoperability, data portals, web services (prioritize important data formats and important data transformations for “back end” systems)

5:00 Summary Reports from Breakout Group Chairs

5:30 Break for Dinner


Day 2 Wednesday 2 March 2005


8:00 Continental Breakfast at the Synthesis Center

8:30 Session 2: Visualization Systems. Extended visualization developer talks (Chair TBD)


Keynote talk by Paul Morin (via videoconference) with an overview of visualization technologies supported by GeoWall. GeoWall supports many visualization packages and as such has become a bit of a clearing house for 3D technologies.


9:00 Each developer will have 15 minutes to speak and 5 minutes for Q&A from the audience.

- Integrated Data Viewer/IDV (Unidata,, Don Murray

- Vista/TeraShake (SDSC,, Amit Chourasia

- GeoFusion (, Chuck Stein

- ESRI/ArcGlobe ( TBD

- Center for Research in Computing and the Arts (CRCA,, Todd Margolis and Sheldon Brown (Includes summary of EVL, U. Illinois at Chicago activities,


10:40 Break


- NASA/JPL (, Kevin Hussey and Lucian Plesea

- GMT (U. Hawaii,, Paul Wessel

- Augmented Reality (SDSC,, Matt Clothier

- EarthVision (Dynamic Graphics,, Skip Pack

- GRASS (NC State Department of Marine, Earth and Atmospheric Sciences,, Helena Mitasova


Topics to be covered in developer presentations:

  • Types of data handled
  • Detailed feature descriptions
  • How software can address science problems
  • Current "choke points" of the tools
  • Future developments
  • GEON participation
  • Q&A from audience


12:40 Lunch


1:30 Wrap up summary of morning technology presentations from session chair. Charge to afternoon breakout sessions.

1:45-2:45 Breakout sessions. The actual topics will depend on the outcomes from Tuesday’s breakout groups.

Possible topics include:

  • Science integration
  • Visualizations and models
  • Hyper dimensional data files (4D and multiparameter)
  • High-end commercial software (e.g. Landmark)
  • Publishing 3D-4D publications (work and visualization)


2:45 Break


3:00 Breakout Group summary presentations, wrap-up of Group discussion

GEON action items, plans and priorities for the next 12 months, and meeting summary


4:00 Conclusion of Workshop
