GEONETCast is a near real time, global network of satellite-based data dissemination systems designed to distribute space-based, air-borne and in situ data, metadata and products to diverse communities.

GEONETCast is a Task in the GEO Work Plan and is led by EUMETSAT, the United States, China, and the World Meteorological Organization (WMO). Many GEO Members and Participating Organizations contribute to this Task.The current partners within the GEONETCast initiative include the China Meteorological Administration (CMA), the National Oceanic and Atmospheric Administration (NOAA), the World Meteorological Organization (WMO) and EUMETSAT, as well as many prospective data provider partners.

The GEONETCast Toolbox is offering a set of utilities that facilitate easy import of various satellite and environmental data / products that are disseminated via GEONETCast, into a common GIS environment.

Aim of GEONETCast
GEONETCast is a milestone in the emerging Global Earth Observation System of Systems (GEOSS) that is being coordinated by the intergovernmental Group on Earth Observations (GEO), and is designed to put a vast range of essential environmental data at the fingertips of users around the globe. This user-driven, user-friendly and low-cost information dissemination service aims to provide global information as a basis for sound decision-making in a number of critical areas, including public health, energy, agriculture, weather, water, climate, natural disasters and ecosystems. Accessing and sharing such a range of vital data will yield societal benefits through improved human health and well-being; environment management, and economic growth.

Within the existing framework, GEONETCast is already partially realising this goal with environmental data exchange and data delivery available in Europe, Africa and the Americas. An additional data exchange is now being established covering the Asia Pacific region.

The following products and services are being made available to the GEONETCast user community:

  • Meteosat image data
  • GOES East and West image data
  • FY-2 image data
  • Land and Ocean Sea Ice Satellite Application Facility (SAF) products
  • EUMETSAT meteorological products
  • NOAA-NESDIS meteorological products
  • NOAA-NESDIS Ocean colour and sea surface temperature products
  • VEGETATION products from VITO
  • MODIS Ocean colour products
  • In-situ and observational data

GEONETCast Infrastructure
The conceptual idea of a global GEONETCast implementation is that several regional centres take on the responsibilities for establishing a satellite-based regional dissemination system — based upon Digital Video Broadcast (DVB) technology — and provide complementary services to a common user community.
