GEONETCast Partners GEONETCast is a system uniting regional data dissemination systems: • • • EUMETCast (EUMETSAT): Europe, Africa, and the Americas FengYunCast (Chinese Meteorological Administration): Asia and parts of Pacific GEONETCast Americas (NOAA): North, Central and South America GEONETCast Americas • • • • NOAA-maintained portion of global GEONETCast system. Operational in 2008 DVB-S Standard on C-Band, bandwidth 2mb/sec. Broadcasting over North, Central and South American and Caribbean. • Provides derived products (non L1 satellite data, warnings, alerts, geolocated imagery, etc) in 9 GEO Societal benefit areas: – – – – – Disasters Health Energy Climate Water - Weather - Ecosystems - Agriculture - Biodiversity Publishing products to GEONETCast Connect to the broadcast server and upload files through FTP, either automatically or interactively. File transfers can be easily automated for routinely scheduled earth observation products. Products created on ad-hoc basis (such as emergency response maps and documents) can be uploaded at any time. At the Receiving Station: Files from selected files are downloaded inmediately to the designated folder. User takes the files and uses them on his/her application Example: Individual files received through GEONETCast are turned into an animation at the receiving station using additional tools. E.g.: c:\>gifsicle -l *.gif > animacion.gif Using client software (like SERVIR Viz, Google Earth or ARC GIS) information downloaded from GEONETCast can be combined with other data sources for further analysis GEONETCast User Interface Software installed on the receiving workstation: •User friendly •Web based •Allows user to activate or deactivate “channels” as wished •Supports automation of tasks Product Samples GEONETCast and Pacific Coverage • • Current broadcast areas do not cover all of Pacific Region – GEONETCast Americas covers continental North, Central and S America, contract option for additional beam to HI and AK – China Meteorological Administration (CMA) provides coverage through Asia and parts of Southwestern Pacific – Funding within NESDIS for expansion of GEONETCast Americas beyond current capability not foreseen. Initial discussions with regional actors on potential expansion scenarios are underway GNC Expansion into Pacific • Questions for Discussion: • Regional user requirements – Operations – Products – Capabilities • New broadcast node or extension of current regional broadcast (GNC-A or FENGYUNCast) • Funding, infrastructure, programmatic support. – Initial baseline estimates of expanding current broadcast capability to offer limited add’l Pacific coverage - • Direct Services Contact Information Kay Metcalf • Marlin O.
