System of Systems Some … Facts & Recommendations System of Systems Some … Facts & Recommendations

Facts & Recommendations (1/4) • Variety of users: institutions, value added companies, private sector, Facts & Recommendations (1/4) • Variety of users: institutions, value added companies, private sector, academic, science, . . Users’ requirements and expectations vary a lot. – Users to be closely associated to any design process as well as Systems Designers, Systems Operators, Data providers, . . – Close coordination with all users from all GEO tasks. • Various communities with own habits: data & information providers / users with specific system interfaces & data formats, own ways of processing information, . . – No revolution to be imposed in work habits but promote alternatives if needed.

Facts & Recommendations (2/4) • No Single System: Heterogeneous sets of world-wide distributed systems Facts & Recommendations (2/4) • No Single System: Heterogeneous sets of world-wide distributed systems built over several years. Different technologies based on multitude of standards, proprietary solutions, in-house developments, . . – No new single architecture imposed to everyone. , – Preserve the existing infrastructures as much as possible, – Simple and robust interfaces and formats (well documented, based on common and largely used standards/specifications). – Need for an Overall GEO Interface Control Document – Overall Coordination at interface level between all GEO tasks teams. – Progressive integration of thematic systems (whenever needed ! To be defined …) • Combined sources: Increasing user request for combined use of space and non-space data e. g. multi satellite missions with in-situ observation data – Need for proper inter-task coordination whenever needed / applicable

Facts & Recommendations (3/4) • Complex information flow: e. g. product order, satellite planning, Facts & Recommendations (3/4) • Complex information flow: e. g. product order, satellite planning, data acquisition, processing, archiving and distribution – Proper (exhaustive) inventory of needs & adequate solutions to be proposed. • User Interface: Increase demand from users for enhanced quality of geo-spatial data, information and services with more user-friendly, faster, easier and transparent access – Users to be involved during the whole executions of task sheets – Prototypes to be developed if necessary

Facts & Recommendations (4/4) • Dependency between GEO tasks: risks that optimum solutions (technical, Facts & Recommendations (4/4) • Dependency between GEO tasks: risks that optimum solutions (technical, programmatic, data policy, . . ) for a given task are sometimes incompatible across-task – Regular monitoring across ALL tasks – Proper overall coordination • Open system: the So. S should be opened enough to grow & attract third-party data & service providers – Use of open architecture (simple, open and stable standards, non-proprietary solutions, . . ) – Combination of services & data “validated/approved” by GEO and others not “GEO-stamped”
