IEEE Geoscience and Remote Sensing Society


The standards and interoperability forum

ADC Co-Chair Meeting 19 July 2006


Strawman a process for reaching geoss interoperability arrangements

Strawman: A Process for Reaching GEOSS Interoperability Arrangements

  • A Standards and Interoperability Forum (SIF) will be created

    • To carry out impartial review and to recommend solutions to GEO interoperability issues.

    • Membership in the SIF will be open to any GEO member or Contributing Organization.

  • The process is to be initiated by those who are attempting to implement a particular GEO Task.

ADC Co-Chair Meeting 19 July 2006


Guiding principles of the sif

Guiding Principles of the SIF

  • The SIF will encourage broader use of existing standards as one factor in recommending interoperability arrangements.

  • The SIF will consider existing international standards organizations and institutes as a focal point for the GEOSS interoperability objectives.

  • In rare cases where no existing standard fulfills GEOSS needs, the SIF could identify appropriate Standards Development Organizations (SDOs) to carry out the standards development process.

ADC Co-Chair Meeting 19 July 2006


Sif outstanding issues

SIF - Outstanding Issues

  • Contents of Interoperability Registry

    • Initial “arrangements” mentioned in 10-yr Implementation Plan Ref. Doc., e.g. ISO 19115?

    • Protocols adhered to by “initially identified systems” that would be available to other GEOSS components?

    • Or should it be only those “arrangements” agreed to as part of the “Process” in which specific interoperability issues are resolved?

  • "All interface implementations should be ... verified through interoperability testing and public demonstrations." [Reference Document]

    • Does this apply to all interoperability arrangements?

    • Who certifies compliance?

ADC Co-Chair Meeting 19 July 2006


Ieee ceo standards working group

IEEE CEO Standards Working Group

  • Working background on standards issues for GEO since May 2005

  • Will serve as consultative body for the SIF

  • Completing 3 tasks:

    • Compilation EO portals

    • Survey of standards in use by EO systems

    • Characteristics of SDOs

ADC Co-Chair Meeting 19 July 2006


Standards in use survey

Standards In Use Survey

  • Question 1: Data Formats

  • Question 2: Metadata Standards

  • Question 3: Catalog Interoperability Standards

  • Question 4: OGC Standards

  • Question 5: Data Acquisition Standards

  • Question 6: Archival Standards

  • Question 7: Interoperability

  • Each Question also asks: What factors did your organization consider in choosing these standards?

ADC Co-Chair Meeting 19 July 2006


Sdo characterization

SDO Characterization

  • Scope of technical activities

  • Who may participate?

  • Scope of participation - National, Regional, International

  • Requirements for initiating a new project

  • Process for approval of new project

  • How leaders are appointed or elected

  • Who may provide proposals or contributions for the standard?

  • Process for development of consensus

  • Timeframes for development of a standard

  • Who may vote (ballot)

  • Process for approval of the standard

    • maintenance procedures, review, revision, and reaffirmation

  • Availability of standard (cost, access, etc.)

ADC Co-Chair Meeting 19 July 2006


Sdos characterized by iswg

SDOs Characterized by ISWG

  • ISO

  • IEEE

  • W3C

  • OGC

ADC Co-Chair Meeting 19 July 2006


Future activities

Future Activities

  • Based on Portal Survey, suggest models for GEOSS Portal to DA-06-07.

  • Make “Standards in Use” survey available via the Web.

  • Publish SDO characterization on the Web.

  • Recommend initial content for Interoperability Registry.
