The Global Earth Observation System of Systems GEOSS

The Global Earth Observation System of Systems (GEOSS) Siri-Jodha Singh Khalsa National Snow and Ice Data Center sirijodha. khalsa@ieee. org

Briefly. . • GEOSS origin, structure & goals • GEOSS Architectural Principles • Current activities

Background • Group on Earth Observations (GEO) – established by 3 ministerial-level summits – includes 72 member countries, the European Commission, and 52 organizations with a mandate in Earth observation • The vision of GEO is to create a Global Earth Observation System of Systems (GEOSS) to help realize a future wherein decisions and actions for the benefit of humankind are informed via coordinated, comprehensive and sustained Earth observations and information.

Structure • • GEO is governed by a Plenary and an Executive Committee – Membership is voluntary and decisions are by consensus Members agree to a 10 -year Implementation Plan, which outlines how GEOSS will work – Focused on nine “Societal Benefit Areas” – The Work Plan consists of over 100 individual tasks Four Committees to guide the implementation of the 10 -Year Plan. – Organized around “transverse” areas of GEOSS development: architecture and data, capacity building, science and technology, and user engagement – Interested Members and Participating Organizations contribute to these tasks, which are overseen by one of the four Committees The GEO Secretariat supports the Members Committees in carrying out the tasks described in the Work Plan

Not Starting from Scratch • GEOSS is being built initially from existing systems and initiatives – emphasis is on the creation of synergies among contributed components – idea is to leverage existing programs and established standards wherever possible, while broadening convergence of systems based on interoperability arrangements agreed to by consensus

Whole is Greater than Sum of Parts • Contributed components should combine to produce an overall system that is capable of providing data and information to meet societal needs better than the individual components operating in isolation. • Such a system is driven by user needs, supports a broad range of implementation options, and is able to incorporate new technology and methods as they emerge. • Contributed components include observing, processing, modeling and data dissemination capabilities that are provided by GEO Members and Participating Organizations.

Interoperability Arrangements • No attempt to build a monolithic data system through which all earth observation data will be managed • Systems contributed to GEOSS continue to operate within their own mandates • But systems should also be designed or adapted so their interfaces support interoperability • Interactions between systems take place according to agreed-to “Interoperability arrangements” based on non-proprietary, open standards

Core Components • Fundamental to the operation of GEOSS is access to information about its components. – Contributed components are described in the “Components Register” – The services these components offer are described in the “Services Register. ” – The interoperability arrangements used by GEOSS components are described in the “Standards and Interoperability Register. ” • All GEOSS registries are interoperable and accessible via the GEOSS Clearinghouse • The GEOSS Portal is the gateway to all of GEOSS

Appendix - Progress Report, Capetown Summit

The Cape Town Ministerial Summit 2007 Earth Observation for Sustainable Growth and Development The Summit allowed: • To highlight early progress of GEO and key achievements in the Implementation of GEOSS; • To bring emerging priorities to the attention of Ministers; • For Ministers to commit to these priorities through The Cape Town Declaration.

The Cape Town Ministerial Summit 2007 The Summit was the opportunity: • To highlight early progress of GEO and key achievements in the Implementation of GEOSS (The First 100 Steps to GEOSS, The Full Picture) • For Ministers to commit to emerging priorities through The Cape Town Declaration.

The Cape Town Declaration • Value of Earth Observations • Data Sharing Principles • Commitment to Sustainable, Interoperable Systems • Protection of Frequencies • Need to Explore Ways and Means for the Sustained operations of… …GEOSS Components

Priorities for the 2008 -2010 timeframe • • • Harmonisation of portals (data and services) Ensuring sustainability of observing systems Bringing new funding Cost benefit analysis Iridium NEXT
