Geospatial Working Group Charter


The Geospatial Working Group develops 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 tools and open international standards can ensure that 3D work can remain accessible and repeatable for years to come. Motivations are:

  • 3D geospatial content needs to be openly available over the long term
  • Using standards-based 3D minimizes future rework
  • Provide a strong foundation that can take advantage of emerging technologies


The Geospatial Working Group applies the Web architecture, XML languages, and open protocols to build a standards-based specification usable by governments, industry, scientists, academia, and the general public. Geospatial efforts encompass client-side, server-side, authoring, and data-conversion technologies. Specific objectives include:

  • Ease presentation and interaction with public and private geospatial data in 3D
  • Integrate geospatial capabilities with X3D technologies to maximize interoperability
  • Evolve the specification to meet the needs of the geospatial community

The mission of the Geospatial Working Group is to promote spatial data use within X3D via open architectures and our vision is to make it easier to create and use 3D spatial data.


The Geospatial Working Group follows the practices declared in Working Group Practices.


The Geospatial Working Group holds a monthly teleconference and annual face-to-face meetings at the Siggraph and Web3D conferences.


Primary Geospatial Working Group efforts are discussed, coordinated and performed within the "safe haven" of a Web3D Consortium working group. Group membership is restricted to members of the Web3D Consortium.  Working group discussions occur on the mailing list (subscribe).  Public inquiries are welcome, either on the mailing list (subscribe) or else directly to the Working Group co-chairs.

Dependencies and Liaisons

Web3D Consortium members include commercial companies, nonprofit organizations, government agencies, academic institutions and individual professionals. Liaison efforts are fundamentally important to ensure that successful results are interoperable with existing and future infrastructures for the Web and the international geospatial community.
  • Open Geospatial Consortium (OGC)
  • World Wide Web Consortium (W3C)
  • The Synthetic Environment Data Representation & Interchange Standards (SEDRIS) Organization
  • International Standards Organization (ISO) ISO/IEC JTC 1/SC 24


Working group communications are published in the Geospatial members-only mailing list. At the discretion of the Working Group, information may also be released to the public.


The Geospatial Working Group maintains a Working Group page on the Web3D Consortium website and a members-only mailing list.
