6. GEONETCast.. a near real time, global network of satellite-based data dissemination systems providing environmental data to a world- wide user community http://www.eumetsat.int/Home/Main/DataA ccess/EUMETCast/SP_201005191146246 75?l=en

7. GEONETCast Infrastructure Satellite-based regional dissemination system — based upon Digital Video Broadcast (DVB) technology GEONETCast Broadcast Streams – EUMETCast Europe, Africa and the Americas Established in 2004 More than 2,000 registered reception stations More than 1,600 users – CMACast (China Meteorological Administration’s contribution) Utilises the AsiaSat 4 satellite beam to broadcast data and products to a user community in the Asia Pacific region. – GEONETCast-Americas Broadcast covering the Americas, managed by NOAA

8. GEONETCast interconnection to GEO-DAB/GCI Entry point Transfer Protocol

9. GEO DAB GEONETCast downlink XDB GEONETCast Data Server GI-NETCast User file system Harvesting OAI-PMH Harvesting OAI-PMH Broadcasting DVB Broadcasting DVB Local storing XDB Local storing XDB Local discovery GI-NETCast Local discovery GI-NETCast

10. General Approach 1.EUMETSAT Data Server uses the GEO-DAB harvesting interface to download all the available GCI (metadata) records 2.GEONETCast satellites broadcasts the harvested GCI to GEONETCast users 3.Users Data Server updates the local DB with the received (broadcasted) content 4.Users discovers and evaluates the local DB content using an adapted (offline desktop) version of the EuroGEOSS GEO-DAB client

11. Harvesting and broadcasting requirements Satellite traffic MUST be reduced as much as possible, GCI provides millions of entries Satellite throughput is limited, large files MUST be avoided GCI records are not static, GEONETCast user DBs MUST be updated (near real time)

12. GI-NETCast requirements Good performances on low cost PCs Portability on different operating systems and hardware Provide (at least) the basic discovery features (i.e. search by keywords, area and temporal period) via a user friendly GUI

13. GI-NETCast: query

14. GI-NETCast: query results

15. GI-NETCast: browsing

16. Future work Interoperability test is the basis for one of the Showcases that will be proposed for the Ministerial – providing the basis for access and use of GEO data and serves in countries with limited internet access Interoperability test with the 52N GEONETCast Toolbox Software.
