A first evaluation of the new CEMS systematic global flood monitoring product

The GlobalFlood Monitoring (GFM) product of the Copernicus Emergency Management Service (CEMS) will soon deliver global,near-real time flood extent maps for each newly acquired Sentinel-1 Interferometric Wide Swath image.The GFM product output will be available with in a maximum of 8 hours following image acquisition. It will consist of 11 output layers including maps of observed water and flood extent, together with classification uncertainty. In this study, we evaluate the observed flood exten layer with the associated classification uncertainty information
