2. GEO Task IN-05 GEOSS Design and Interoperability Priority Actions GEOSS Information System research and prototyping Societal Benefit Area needs drive development Encourage systems to interoperate with GCI Increase access to GEOSS Data-CORE Coordinate with IN-03 GCI Evolution Recent Progress and Key Outputs for 2013 Architecture Implementation Pilot (AIP) Standards and Interoperability Forum (SIF) GEOSS Future Products Workshop

3. GEOSS connects Observations to Decisions

4. GEOSS Interoperability Arrangements - From the GEOSS 10 Year Plan Reference Document - Interoperability through open interfaces –Interoperability specifications agreed to among contributing systems –Access to data and information through service interfaces Open standards and intellectual property rights –GEOSS adopting standards; agreed upon by consensus, preference to formal international standards –GEOSS will not require commercial or proprietary standards –Multiple software implementations compliant with the open standards should exist –Goal is that at least one of the implementations should be available to all implementers "royalty-free"

5. Architecture Implementation Pilot (AIP) Deploy and test new components for GCI and the broader GEOSS Information System –Agile, evolutionary development process –Sprints to identify architecture standards and improve maturity of components AIP initiated in 2007; 5 previous phases completed –Deployed, test, demonstrated: GCI, Brokers, Community Portals, SBA Integrators, etc. AIP-6 currently underway, delivery for Summit

6. Architecture Implementation Pilot AIP-1 Kickoff: Jun 2007; Alpha operations Nov 2007; Arch Workshop Feb 2008AIP-1 –"Core" Architecture as initial GCI AIP-2 Kickoff Sep 2008; demo ISRSE May 2009; Beta operations Sep 2009AIP-2 –Refined GCI supported transition to operations AIP-3 Kickoff Mar 2010; results to Beijing Plenary; Complete Feb 2011AIP-3 –SBA Scenarios; Piloted Broker and Processing capabilities –GEOSS Architecture Progress video for Beijing Ministerial - linklink AIP-4 Kickoff May 2011; results to Istanbul Plenary; Complete Dec 2011AIP-4 –Increased access to priority EO data AIP-5 Kickoff May 2012; results to Brazil Plenary; Complete Mar 2013AIP-5 –SBA application scenarios; GCI research AIP-6 Kickoff March 2013; results to Ministerial; Complete 2014AIP-6 –Ministerial Showcases

7. AIP Results Integration of disciplines thru architecture Geo-informatics results… –Initial GCI prototypes –Brokering to span communities –Moving from “order” to “access” for rapid delivery –Fusing EO data with other geospatial information, –Sensor Web to hide complexity of diverse sensing systems and associated control structures. –Model Web vision promising with initial steps …apply across SBAs: Disaster Management, Biodiversity Models, Energy, Water, Health

18. Summary: Integration across disciplines in GEOSS AIP development approach combines the best of prototyping and specifying Architecture developed in AIP provides a basis to scale to multi-disciplinary needs in GEOSS. Standards and interoperability arrangements support fusion of EO observations across disciplines AIP and other GEO Tasks show the value of GEOSS in application of EO to meet societies needs
