GSCB Work Plan
Based on an initial 3-year plan defined at the end of 2005, GSCB began to work on the more critical domains for which harmonisation at the European level would bring cost savings in the ground segments and a discernible improvement in access to the EO data for users and service providers.
The first (and main) project, the Heterogeneous Mission Accessibility (HMA) study, aims at the joint definition and adoption of interoperability standards required to guarantee seamless and harmonized access to heterogeneous EO datasets.
The initial step is to define standards for the discovery, cataloguing, ordering, accessing and delivery of EO data. To do this, the GSCB is relying on the experience of its members, while following international standards and coordination with the European Commission’s INSPIRE programme.
The first standardisation version through the Open Geospatial Consortium (OGC) and the European Committee for Standardisation (CEN) is targeted for 2007, with initial implementation in 2009. Standardisation through the European Cooperation on Space Standardisation (ECSS) will follow.
The following steps of the project are devoted to defining the harmonized format of EO data products and their quality certification and reporting. The first milestone for the data and quality harmonisation definition is 2008.
The second project is the definition of the Payload Ground Segment reference architecture by identifying the different building blocks and interfaces, and exploiting the experience of the different ground segment operators.
The adoption of a reference EO ground architecture for a simple, user-friendly, cost-efficient and inter-operable infrastructure will eventually be recommended, to:
The third project is the definition and adoption of a common strategy for the long-term preservation of EO data. The strategy will define the technical and managerial approach and provide recommendations for data access, security and archive operations, maintenance and evolution, including data reprocessing and data integrity.
The activity will capitalise on policies already in force for preserving digital data archives (at ESA, national space agencies, Eumetsat) and will consider European Union initiatives like the CASPAR project. The first strategy proposal is planned for 2007.
