The document discusses providing web-based access to real-time GEONETCast satellite data for geochange research. GEONETCast is a satellite-based dissemination system that provides 180 global data products free of charge. A technical setup is described to receive and serve the GEONETCast data through interoperable OGC web services, allowing query of real-time and historic data from a web client. An example of accessing raw MSG-2 meteorological data at 3km resolution every 15 minutes from a WCS is provided. The conclusion discusses providing open, web-based access to both real-time and historical GEONETCast data through open-source software.
Web-based GEONETCast Data for Geochange Research
