12 Step Program Meeting: How to Survive Death by Powerpoint

1
12 Step Program MeetingHow to Survive Death by
Powerpoint

• X3D Earth Technical Requirements Workshop
• Naval Postgraduate School,
• Monterey California, USA
• November 14-15, 2006

2
Proposed workshop conclusions
or what have we learned today? what do we do
tomorrow?

• X3D Earth Technical Requirements Workshop
• Naval Postgraduate School,
• Monterey California, USA
• November 14-15, 2006

3
What Were 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

4
What Were 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

5
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

6
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

Additional points to consider
8
Wednesday Activity

• Mashup/Matchup unneeded, were close already
• Lets think about how to build X3D Earth
• Candidate End User Needs, Requirements, Use Cases
• Identifying Relevant User Communities
• Candidate Technology Requirements a looong list
• Outreach Interoperability Strategies, many
  players
• OGC, ISO, W3C, Web3D, others
• Possible Positioning and Marketing
• Multiple parts of earth land, subsurfaces, sea,
  space, environment, hooks for physics, etc.

9
Reaching Out to Industry

• Importance?
• How to?

10
Cross Connect Technologies Align Format
Semantics, Build Converters

• OGC family
• KML

11
Other Technologies, Products, Projects

• Microsoft
• MegaCarta
• VTerrain (open source)
• ESRI Arcview, CJMTK
• AGI Satellite Tookit

12
What showstoppers or major difficulties
prevent us from creating X3D Earth?
13
What are the sizing requirements for X3D Earth
storage?
14
Questions from Sonalysts Inc.

• Photogrammetry, LIDAR, and manual surveys are all
  methods for gathering raw data for X3D simulated
  environments.  Are there other methods?  Can you
  describe them?
• What is the quickest method to convert a raw data
  set (a LIDAR map, for example) into X3D models? 
  The most accurate method?  The best method?
• Can X3D models be automatically created from raw
  data, that is with no or minimal human
  interaction?
• How was the Pearl Harbor map created?
