10 Service Viewpoint: Overall Goal: a standardized, harmonized set of interfaces that support a service oriented view of the heterogeneous mission ground segments, which can be implemented in a cost-effective manner; enabling the construction of compound / value added services from basic interfaces. Discovery (collection, services) Catalogue (earth observations) Order (archive, subscription, on-line access) Programming (order for acquisitions, mission planning feasibility) Data Access (ftp now, wcs future) Data Portrayal (wms) Service Orchestration [ Identity Management, Monitoring & Control...] Slide 10

11 Discovery Use of UDDI for service configuration management, and for COTS tools oriented schema interrogation and service chaining CSW ISO profile found broadly applicable for collection and service metadata discovery providing association between collection and service providing geographic extent to services ESA supporting development of ebrim extension pacakage for 19115/19119 OGC Slide 11

19 Lessons Learned Protocol definition and standardisation: time & resource consuming process OGC process very open, convergence very slow CEN Workshop Agreement easy to manage for project specific scope Identity management: GCM requirements are very challenging in a federated scenario, COTS and Open Source available but integration is far from straightforward Trade off between requirements and implementation options needed Security ISO very useful in a multi partner context Information Security Management System implications still to be addressed Slide 19

20 Subjects for Future Work Online data access requires short term - additional work to cover consistently multiple sensors (optical, radar, atmospheric) and data use scenarios (WCS, JPEG2000, ) see requirements from Spot Image Several areas of GS interoperability medium term - deserve a dedicated effort (e.g. mission analysis and planning, station resource sharing, ) see requirements from Spot Image, Pleiades Complex scenarios long term - mission in the loop require extensive technical and organisational analysis extends e.g. Radar Constellation-CSA, SABRINA-ASI Slide 20

21 Next Steps: Standardisation Identity management and on-line data access activities ongoing Identity Management Prototype review June 2007, CEN Workshop Agreement to be signed current project to complete by September 2007 current version of catalogue related standards to be finalised by OGC revision WG by end of year -Testbed Provides ( mid 2009) ITTs planned mid 2007,mid 2008 to support uptake by industry COTS vendors have announced EO catalogue support before end 2007, OGC adoption should enlarge the uptake Discussion ongoing with GeoNetwork (FAO) to support ebrim A persistent testbed in order to support the implementation and OGC conformance testing of products and GSs Support to OGC Interoperability Pilot FedEO Federated Earth Observation kicked off in ESRIN on 5-6 June see as well GEO Call For Participation at Architecture Board Charter shall ensure governance of standards evolution Slide 21

22 Next Steps: in products and quality GMES PRODUCTS HARMONISATION : STUDY PHASE - ITT Published on EMITS AO5367 Objective: understanding of the needs for Level-1and Level-2 product harmonisation, guidelines for ESA Sentinel-s missions products definition. Vertical harmonisation: compatibility within the same sensor group. Candidates for harmonisation: geophysical parameters e.g.. chlorophyll, vegetation index, sea surface height, etc. auxiliary data parameters, algorithm parameters or processing parameters. Horizontal harmonisation: compatibility across different class of sensors and Sentinel-s groups. Candidates for harmonisation product format spatial resolution. GENERIC ENVIRONMENT FOR CAL/VAL ANALYSIS (GECA) - ITT Published on EMITS AO 5253 Objective: standard, exchange mechanisms and tools for communication of a-posteriori product quality information and related corrective actions. Correct application of data products requires knowledge of quality and deficiencies, those that are detected at the time of product generation, are included in product confidence records. The more complex deficiencies that are detected through data quality analysis require: a means to communicate quality analysis results and instructions electronically to the tools of the end users. That traceable corrections are applied, in contrast to the current situation where users must read anomaly reports and manually adapt their code at each detection of a new anomaly. GEO CEOS Workshop on Quality Assurance of Calibration and Validation Processes Geneva 2 4 October 2007 To identify and scope key elements needed to develop and implement a "data quality strategy" as required by GEO task DA-06-02: Best practises in Cal / Val Processes. Harmonisation and Standardisation of Quality Control and Calibration / Validation Processes. The role of CEOS in the Certification of those processes. Implementation Strategy. Slide 22

23 Next Steps: Implementation in GMES EO-DAIL ITT published on EMITS AO5368 GCM: Implementation contracts with GCM to be financed by ESA GMES Implementation KO Planned 4Q2007 The GMES Data Access will be implemented following a phased approach: V0, the as-is (initial baseline) of the current existing infrastructures (ESA and GCM). GSC pre-operations V1.0, Data Access based on data provider firm agreements (SLAs) to serve the initial set of core GMES services and potentially increased by European Commission recognized new services, operations target date: Q Harmonized GSC infrastructure V2.0, the Heterogeneous Mission Access () will be in place, harmonised products (as far as applicable) will be offered through the data portfolio. New GMES services may be included following EC agreement; operations target date: Q GSC Evolution V3, Including any necessary evolution identified during the V2.0 lifecycle (e.g. data portfolio support, new services, system component evolution).
