X3D Earth Technical Requirements Workshop

Requirements, Capabilities, Challenges, Partnerships and Next Steps

Naval Postgraduate School, Monterey California USA, 14-15 November 2006

All Participants    3-Way Video

Summary of X3D Earth goals. Web3D Consortium members are preparing to build a standards-based X3D Earth usable by governments, industry, scientists, academia and the general public. X3D mappings of world terrain, cartography and imagery will be made available for use in any scene, making it easy to geospatially reference and share X3D models. Open standards, the Web architecture, XML languages and open protocols will be used throughout. Both commercial and open-source software codebases will be able to utilize these best practices and contribute to these shared assets.

Workshop goal. Participants identified and prioritized the technical requirements, available capabilities, open challenges and strategic partnerships needed for a Web3D working group to execute this ambitious project. Emphasis was placed on extensibly adapting existing resources and cooperating to achieve shared goals, especially with other open geospatial organizations and standards. Workshop results document participant contributions, next-step activities and goal milestones.

Quicklook Summary

The workshop was well attended and very productive. Participants spent the first day looking at many relevant technologies, capturing potentially relevant technical capabitilies and requirements as they proceeded.

A workshop report is being reviewed and will be distributed publicly.

The following preliminary conclusions were drawn.

What We’re Seeing

  • Lots of compelling success stories
  • Apparently composable technical approaches
  • Complementary standards and organizations
  • Diverse disconnected projects
  • Confluence, overlap, agreement
  • Substantial discussion on many overlapping points of interest

What We’re Not Seeing

  • Coherent use cases for design requirements
  • Major controversies or major conflicts
  • Any other common-denominator 3D format
    • although not everybody is here today
    • and what about maps?
  • Confusion about what is needed next
  • Detailed server architecture, context etc.
  • How is it different from all the other “earths”

Observations

  • Commercial products appear to have best quality, but free versions can be competitive
    • NASA WorldWind demo was compelling
  • Numerous data products available openly, from governments etc.
    • similar or better coverage to commercial products
  • Commercial products appear to be serving different end users

Preliminary Conclusions

  • X3D Earth is feasible
    • This effort can be started now
  • Many resources are already available
    • Work needed to make them compatibly available
  • No showstoppers found
    • A nice surprise after so many diverse inputs
  • Lots of collaboration and coordinated work are needed to proceed successfully
    • Are we building a web-services infrastructure?
    • Server-side specification might be most important activity
