3. Page 3 What is HMA A collaborative project started in Europe and Canada by the Ground Segment Coordination Body (GSCB) in 2005 with the objective to: Guarantee a seamless and harmonised access to heterogeneous EO datasets from multiple mission ground segments, including national missions and ESA missions. Standardise the ground segment interfaces of the satellite missions for easier access to EO data. Provide interoperability for coordinated data access enabling the interactions with services or Value Adders and EO Contributing Missions. HMA-S Final Presentation - 11/06/2014

20. Page 20 Main issues – Lessons Learned OGC Process –Dependency on external votes makes reaching quorum problematic… –Unpredictable timing (e.g. WPS 2.0, Task 3 CR Mgt process) TEAM Engine –Some specifications not suitable for TEAM engine approach testing and test configuration through Web Portal. Client/server configuration for order options, security keys etc. Project Process –Demonstrators with individual separate requirements specification and corresponding test procedures (and subject to individual acceptances) would have facilitated integration. –Difficulty to keep aligned schedule of individual tasks due to different OGC dependencies.

HMA-S provides corresponding reference implementations (open-source) and CITE ETS / CTL scripts. OpenSearch good example of standardisation in CEOS context through the OGC process Further reading: –http://www.esa.int/About_Us/ ESA_Publications/ESA_TM- 21_Heterogeneous_Missions_Accessibility
