  1. Vision and architecture ofGEOSS Information SystemGEOSS Design and Evolution George Percivall The Open Geospatial Consortium (OGC) GEO Task IN-05 coordinator 20 September 2013 ESA/ESRIN Frascati Italy

  2. GEO Task IN-05GEOSS 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. AIP ResultsIntegration 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

GEOSS AIP Architecture Community Objectives Enterprise Viewpoint GEOSS Vision and Targets Societal Benefit Areas System of Systems/ Interoperability Use Cases Services Information Framework Abstract/Best Practices Catalog/Registry Access and Order Processing Services Sensor Web User Identity Earth Observations Geographic Features Spatial Referencing Metadata and Quality GEOSS Data-CORE Information Viewpoint Computational Viewpoint Tutorials Optimized Design/Development Engineering Viewpoint Component Types Technology Viewpoint RM-ODP Viewpoints

  8. Standards and Interoperability Forum (SIF) • Recent Achievements of SIF • Manage registry of standards & special arrangements • Interoperability Assessment Report with recommended metrics for GCI to monitor • Additional tutorials on GEOSS Best Practice Wiki • GEOSS Data-CORE metadata guidance document • 2013 Planned Deliverables of SIF • Additional Tutorials • Mime-types for helper applications in GCI • Quality metadata standards document to DSWG • Whitepapers on select interoperability topics

  9. Policy Decisions GEOSS Future Products Workshop:Sensor Web and Model Web March 2013 • Earth System Models • Oceans • Ice • Land • Atmosphere • Solid Earth • Biosphere Decision Support AssessmentsDecision Support Systems Societal Benefits Interoperabilityand standards • Earth Observation Systems • Remotely-sensed • In situ On-going feedback to optimize value and reduce gaps

  10. GEOSS Future Products WorkshopRecommendations • Products for GEOSS from Sensor Web and Model Web • Use methods of science to guide use of observations and predictions. • Utility of Sensor Web has been shown; development to meet remaining challenges. • Model Web vision should be advanced with a short-term plan • Interaction of Sensor Web and Model Web brings benefits beyond individual use • Address Diversity of GEOSS USERS • Further develop understanding of diversity of GEOSS Users • Authentication and Interoperability Issues advanced with support by SIF and AIP • Going beyond current state of GCI to meet expectations • GEOSS Capacity Building recommendations • Improve public messages for GEO full report posted https://portal.opengeospatial.org/files/?artifact_id=53993

  11. 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
