X3D-Earth Working Group Charter

• Vision. Make it easier to create and use 3D
  spatial data.
• Mission. Promote spatial data use within X3D via
  open architectures.
• Working Group Cochairs
• Don Brutzman, Naval Postgraduate School MOVES
  Institute
• Mike McCann, Monterey Bay Aquarium Research
  Institute

Working Group Charter Motivation

• The Extensible 3D (X3D) Earth project will create
  a standards-based 3D visualization infrastructure
  for visualizing all manner of real-world objects
  and information constructs in a geospatial
  context. Archivability of models using stable
  commercial tools noncommercial international
  standards will ensure that 3D work can remain
  accessible repeatable for many years to come.
• Public and government assets need to be openly
  available over long term, indefinitely
• Huge investment in data preparation, future
  rework/rewrite may not be possible
• Archiving and availability are essential
  prerequisites for many groups
• New spatial capabilities become possible,
  including Semantic Web and search-based
  applications

10
Working Group Charter Goals

• The X3D Earth Working Group will use the Web
  architecture, XML languages, and open protocols
  to build a standards-based X3D Earth
  specification usable by governments, industry,
  scientists, academia, and the general public.
• X3D-Earth efforts encompass client-side,
  server-side, authoring, and conversion
  technologies. Specific technical objectives
  include
• Build a backdrop X3D model of planet Earth
• Use publicly and privately available terrain
  datasets
• Use publicly and privately available imagery and
  cartography
• X3D technologies will be applied to maximize
  interoperability among spatially aware
  implementations
• Provide linkable locations for any place
• Provide hooks for physical models
• Use open standards, extensions and process
• Define functionality in a platform-independent
  manner

11
Working Group Charter Results

• Determining technical requirements and
  overall scope of metadata requirements.
• Scoping group deliverables, products, and
  specifications, also identifying complementary
  standards.
• Enable and provide for compliant
  applications, converters and (especially)
  server-side implementations.
• o Candidate server-side requirements
  include preparation of content,
  interlocking/addressable URL schemes, ability to
  add new X3D Earth content, ability to efficiently
  mirror resources, streaming of relevant X3D Earth
  data, etc.
• o Coordinate the establishment of
  multiple interoperable implementations, including
  at least one open-source implementation
• o Multiple example datasets for each
  capability, including at least one
  publicly-available dataset
• o Provide technical support for both
  distributed and local operation
• Coordinate with X3D Working Group and User
  Interface Working Group to ensure compatibility
  and coherent extensibility of X3D specifications
• Provide detailed goals for a phased rollout
  of X3D Earth products, with twice-yearly release
  milestones and demonstrations
• Execute a broad strategy for deployment,
  dissemination and outreach, diffusion of
  innovation, and widespread adoption.
• Produce formal specifications for
  Consortium and partner-organization review,
  followed by formal ISO standardization.

12
Working Group Participation

• Primary X3D Earth efforts are coordinated and
  performed within the "safe haven" of a Web3D
  Consortium working group. This is the follow-on
  effort to the Web3D Geospatial Working Group.
• Web3D Consortium members include commercial
  companies, nonprofit organizations, government
  agencies, academic institutions and individual
  professionals.
• Membership classes large/standard/small
  organizational, academic, and professional

13
X3D Earth Working Group Intellectual Property
Considerations

• Primary X3D Earth efforts will be coordinated and
  performed within the "safe haven" of a Web3D
  Consortium working group. Working group members
  agree to follow the Web3D Consortium Intellectual
  Property Rights (IPR) policy.
• All patent encumbrances must be predeclared prior
  to working group scrutiny.
• There is a strong preference for only including
  royalty Free (RF) technology.
• Patented submissions used in a final
  specification typically fall under a reciprocal
  license.
