Strategic Targets of Architecture and Data Management (ADM) • Target of Architecture Achieve sustained operation, continuity and interoperability of existing and new systems that provide essential environmental observations and information, including the GEOSS Common Infrastructure (GCI) that facilitates access to, and use of, these observations and information. • Target of Data Management Provide a shared, easily accessible, timely, sustained stream of comprehensive data of documented quality, as well as metadata and information products, for informed decision-making.

Critical Earth Observation(EO) Priorities

Critical Earth Observation Parameters

How many of the parameters are covered by downloadable data sets? Societal Benefit Areas Precipitation Used Soil moisture Surface air temperature Not used Surface wind speed Land cover

Critical EO Parameters Covered by “Downloadable” Data Sets Through GCI EO parameters covered by “downloadable” data sets through GCI. 146 Critical Earth Observation (EO) Parameters 23 Top 25 Important parameters 2 111 or 76％ of Critical EO parameters are now covered. 121 88 EO parametersnot covered by datasets available on-line 33 As of Nov, 2011

ADC Achievements 2011 • Discovery and access (e.g. download) of broader and more heterogeneous EO data products with current technology • “Sprint to Plenary (StP)” • Prototyping of New GCI with EuroGEOSS and GENESI DEC. • Facilitating access to GEOSS Data CORE • AIP-4: supporting StP • Access to critical EO data sets (direct data access) • EO vocabulary (ontology team) • Software tools to access and exploit EO data • Standards and Interoperability Forum (SIF) and AIP-4 • Tutorial; “How to use GEOSS” • “Interoperability Assessment White Paper” by SIF • Based on analysis on GCI uses, identified ways to improve GCI functionality to better supportinteroperability.

Next Steps • Enhance work plan with clear definitions of targets and milestones for ADC tasks, ensuring that the strategic targets are achieved by 2015. • Evolve GCI • Enable access and exploitation of data discovered via GCI, including mobile applications • Support cross SBA applications (e.g. water + health） for development of earth data products and information • Facilitate the expansion of interoperable Earth Data Sets and their incorporation into GEOSS • Better Communication • Create and implement a communication plan (e.g. Tutorial on “How to use GEOSS”)

END

Interoperability Recommendations Recommendation Category 1: Enhance the GCI, including legal interoperability and semantic interoperability, so it is better understood and more usable. Recommendation Category 2: Achieve standards convergence and integration of semantics. Recommendation Category 3: Incorporate metrics into the GCI to monitor interoperability. Recommendation Category 4: Engage communities more to understand their evolution and to cultivate relationships for GEOSS interoperability. Recommendation Category 5:Work with communities to establish a reference architecture and design for community components such as registries and brokers/mediators.

Remaining issues.Monitoring and Evaluation (M&E) WG Report on ADM • No clear evidence that the ADC Strategic Targets will be met by 2015. • User Interface is difficult to use. • No uniform, consistent way that data are registered, stored and accessed. • Lack of Systems Engineering Rigor. • Technology employed is not current. • Data may exist but difficult to find. Planning and Management • No formal process for Gap Analysis between Targets and Tasks. • The present progress report does not allow for a quantitative evaluation of progress. • The GEOSS capabilities are not well communicated to global community. • Commercial and intellectual property rights are perceived as a barrier to publishing data in GEOSS. Technical Communication

Present status of registries in GCI Registered contents • 28,000,000+data products, • 1,500+ services • 500+ EO systems • (as of Nov. 2011) • Data products • Services • User requirements 1,300 + contents (as of Nov. 2011) • Standards, interoperability arrangements 179 (as of Nov. 2011)
