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
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"
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
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 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
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
