GEONETCast Overview

GEONETCast is a good way to access earth observation data…

  • Operational or project data dissemination

  • High data volumes are involved

  • Data timeliness and availability are important (  relevant for alerts)

  • A number of users could benefit from the same data ( relevant for alerts)

  • Regular data extraction is required (hourly, daily, weekly)

  • Data is needed in “low infrastructure” areas or areas of no or limited network (e.g. Internet) availabilities (  relevant for alerts)

GEONETCast Overview

GEONETCast reception stations are

  • Self contained

  • Stand-alone

  • Include data discovery via offline version of the “Product Navigator” ( link to training material!)

  • Of the shelf very low cost systems

    GEONETCast is linked to the EO-portal

  • Online data discovery and indication of data availability via “near-real-time dissemination” on GEONETCast

User & Data Provider Engagement

Each region working directly with its users and data providers;

Coordinating with IGDDS and WIS;

Working with providers such as SERVIR, USEPA, RANET, JCOMM/GOOS, ECMWF, INPE, AMESD, CBERS;

A number of EU Environment and ICT projects include use of GEONETCast – DevCoCast, AIDA, AEGOS, MIA-VITA.

GEONETCast Alert Channel

Proof of concept

Planned prototype implementation using EUMETCast

EUMETCast is EUMETSATs component of GEONETCast

EUMETSAT will use CAP for some of its own products. The MSG Volcanic Ash product will be a CAP data example (see presentation by Simon Elliott)

Geonetcast alert channel12 l.jpg
GEONETCast Alert Channel

Channel based dissemination on GEONETCast

Each product/product category is assigned to a dedicated multicast channel on GEONETCast such as RA-VI BMD, Training Channel, Info Channel, Data Channel 1-4 etc. … and “Alert Channel”

Each channel uses either a dedicated or shared bandwidth for dissemination

Priorities are assigned depending on delivery needs

User groups can be assigned to each channel (access control supported)

Dedicated bandwidth

Channel is kept free of any other data then alerts

Channel is setup for high priority and immediate dissemination

Data exchange to the partner GNCs

NRT availability of CAP alerts simultaneously on the entire footprint
