These records will be displayed as GEOSS DataCore in late March
(Broker will be updated to support the tagging of an entire
catalog)
These records will be displayed as GEOSS DataCore in late March
(Broker will be updated to support the tagging of an entire
catalog)
A new capacity was recently provided by INPE using a new
protocol, this will be available in late march with the new
deployment of the Broker. The number of records is estimated.
The number of records is estimated (due the GENESI DEC
protocol)
Service seems to be down at the moment

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
GEONETCast interconnection to GEO-DAB/GCI

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
Harvesting and broadcasting
requirements
GCI records are not static, GEONETCast user DBs MUST be updated (near real time)
Satellite traffic MUST be reduced as much as possible, GCI provides millions of entries
Satellite throughput is limited, large files MUST be avoided
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
GI-NETCast: query
GI-NETCast:
query results
GI-NETCast:
browsing
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.
Thank you !
