Strategic Targets of Architecture and Data Management (ADM)

• Target of ArchitectureAchieve 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 ManagementProvide a shared, easily accessible, timely, sustained stream of comprehensive data of documented quality, as well as metadata and information products, for informed decision-making.

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 support interoperability.

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”)
