Geoss background

GEOSS Background

  • Administered by GEO (Group on Earth Observations)

    • www.earthobservations.org

    • membership open to UN + EC (currently 72 countries plus EC)

    • participating organizations approved by GEO members (currently 52)

      • intergovernmental, international, regional

      • engaged in Earth observations and related matters

  • Guided by 10-Year Implementation Plan (2005-2015)

  • The Vision:

“… to realize a future wherein decisions and actions for the benefit of humankind are informed by coordinated, comprehensive and sustained Earth observations and information.”

Geoss purpose and scope

GEOSS Purpose and Scope

  • Meet the need for timely and quality global information for addressing societal benefit areas.

  • To utilize contributing systems that span the spectrum from primary data observation to data products.

  • To share data, metadata, and products.

  • Increase sharing of methods for modeling and analysis.

  • To encourage the adoption of existing and new standards that support interoperability and data usability.

ISWG / SIF / GEOSS


Geoss committees

GEOSS Committees

  • Established by GEO to guide the 10-Year Implementation Plan.

  • Architecture and Data Committee

  • User Interface Committee

  • Capacity Building Committee

  • Science and Technology Committee

Geoss core architecture

GEOSS Core Architecture

  • Reached Initial Operating Capability in 2007

  • Core components include

    • GEO Web Portal (3 candidates as of IOC)

    • GEOSS Clearinghouse

    • GEOSS Components Registry (56 as of IOC)

    • GEOSS Services Registry (68 as of IOC)

    • GEOSS Standards Registry (about 90 as of IOC)

Critical GEOSS Use Case

???

ISWG / SIF / GEOSS


Standards taxonomy effort

Standards Taxonomy Effort

  • Required for quick search and discovery of standards and special arrangements.

  • Helps facilitate seamless registration of standards when entering services.

  • Is the first step towards ontology development.

ISWG / SIF / GEOSS


Existing standards taxonomy

Existing Standards Taxonomy

  • Linear, few categories, entries skewed.

  • Too broad to associate well with standards.

  • Let’s take a look!

Standards taxonomy goals

Standards Taxonomy Goals

  • Generate a finer-grained controlled vocabulary with user community input.

  • Associate primary taxonomy category with standards, as well as secondary categories.

  • Use MMI resources and other possible collaborations.

  • Associate the finished product with the GEOSS Standards Registry to enable efficient search for standards to associate with registered services.

  • and …

  • Apply ebRIM, or acceptable profile, association taxonomy to relate Standards Register entries.

Taxonomy examples

Taxonomy Examples

Name: Quality

Definition: Standards specific to the procedures and algorithms

needed to decrease uncertainty and improve validity

of acquired data, and associated processes and

systems.

Parent: Production Cycle Rules and Standards

Name: Quality Assurance

Definition: Standards specific to the design of procedures and

algorithms necessary to provide confidence that

requirements are met prior to data acquisition.

Comment: The phrase 'data acquisition’, and variants, will

include data received from physical sensors,

models, humans, data feeds, etc. May need an

associated category for confidence metrics.

Parent: Quality

Lessons learned

Lessons Learned

  • Involve a separate review group.

  • Limit debate time.

  • Keep track of potential properties and associations for ontological efforts.

  • Adopt common phrases for organization and continuity.

  • Adopt a “glossary” of secondary definitions to support the main vocabulary.

ISWG / SIF / GEOSS


Another standard

Another Standard ?

  • The ISWG is about to issue a CFP to engage in an effort to look into developing a standard, or guide, or best practice, for creating earth observation taxonomies and ontologies, and creating standards taxonomies and ontologies.

  • This will be a collaborative effort with existing resources, assets, and experts.

ISWG / SIF / GEOSS


Best practices registry

Best Practices Registry

  • It is currently a wiki.

  • It is found at:

    • http://wiki.ieee-earth.org/Best_Practices

  • There is an ontology area that has just been formed.

Possible areas of synergy mmi and geoss

Possible Areas of Synergy(MMI and GEOSS)

  • Taxonomy/Ontology collaboration.

    • with ISWG and SIF

    • with new GEO ontology task (can give broader recognition to MMI)

  • Registration of taxonomies and ontologies at MMI.

  • Registration of metadata tools as components and services in the GEOSS registries.

  • Contribution to the GEOSS Best Practices Registry (MMI Guides, Case Studies, etc.).

  • Discussions regarding applications and resources needed based upon GEOSS use cases.

Geoss aip

GEOSS AIP

  • Architecture Implementation Pilot

    • a call for participation to engage the scientific community in deploying requested components, services, portals, etc. that serve as case studies for the GEOSS initiative.

    • a mechanism to test the operating capability of the core GEOSS architecture.

    • Details about the AIP Phase 2 can be found at:

      • http://www.ogcnetwork.net/AIpilot

    • CFP can be found at:

      • http://www.ogcnetwork.net/AIPphase2CFP

  • Submissions requested by Sep. 1, 2008, but will be accepted all through AIP Phase 2.
