Earth observation and Copernicus – the European Copernicus Programme entered its operational phase with the launch of the first Sentinel satellite in 2014. Data from space or – to be more precise – Earth observation data from different missions and in the future primarily that generated by the European Copernicus system – offers an enormous range of potential uses. Combined with and complemented by in-situ data from local and regional sensors or sensor data networks and other geo information, completely new applications can be developed.
