Page 3Overview of the HMA Project, 8 March 2010 What is HMA A collaborative project started by the GSCB in 2005 with the objective To guarantee a seamless and harmonised access to heterogeneous earth observation (EO) datasets from multiple mission ground segments, including national missions and ESA missions. To standardise the ground segment interfaces of the satellite missions for easier access to EO data. To provide interoperability for coordinated data access enabling the interactions with services or Value Adders and EO Contributing Missions.

Page 4Overview of the HMA Project, 8 March 2010 Why HMA –Increased demand for EO data, of different missions –All EO mission play a vital role in addressing global programmes like GMES and Climate Change –The number of missions needed to establish the necessary observation capacity for critical services is ever growing, –Interoperability is needed to reduce the burden to planners and operators!

Page 6Overview of the HMA Project, 8 March 2010 The Standards Objectives –Facilitate the work of downstream users –Exploit geospatial standards and tools –Rely on industry and market driven approaches The solution – we joined the Open Geospatial Consortium… HMA related standards are the result of contributions from Agencies and users, and the work of 25 companies over 10 countries

Page 7Overview of the HMA Project, 8 March 2010 Context "HMA": harmonised interfaces to heterogeneous EO missions Being operationally implemented. Common interfaces for discovery, catalogue, ordering, feasibility analysis, metadata

Page 8Overview of the HMA Project, 8 March 2010 Slide 8 Context HMA based on two track approach: operational implementations and parallel "standardisation and support activities" Standardisation and support activities to: 1.Permit evolution and test of HMA interoperability standards in parallel with operational implementation of EODAIL and interfaces I/F with Partner G/S. 2.Support conformance testing of HMA adopted standards. 3.Support implementation of HMA defined standards by European Institutional Users and geospatial software product developers

Page 22Overview of the HMA Project, 8 March 2010 How changes to the standards are managed on the HMA side The HMA Architecture Working Group - HAWG is in charge of the Configuration Management and the coordination of the HMA standards between several agencies. the HAWG performs two sets of activities: manage the evolution of the standards baseline used within the implementation at ESA and within HMA AWG members prepare the future evolutions and orientations of the HMA standards.

Page 23Overview of the HMA Project, 8 March 2010 Conclusion HMA related OGC standards have been implemented by various organisations either as open source or COTS Documents describing ongoing work and software available at wiki.services.eoportal.org Evolution is mainly in new areas: –To comply with evolutions of OGC base standards –To address requirements in online data access, processing, semantic interoperability –To address scientific and mass market communities
