worldwater Round robin update
Over the years there has been many promising studies on EO-based surface water mapping, but a systematic evaluation of algorithms and models is lacking. Therefore, the WorldWater project has organized a Round Robin inter-comparison of 15 models for monitoring inland surface dynamics with Sentinel-1, Sentinel-2 and Landsat 8 imagery. The objective was to achieve a better understanding of the pros and cons of different sensors and models for surface water detection and monitoring.
The initial Round Robin results indicate that single sensor approaches can produce accurate and consistent water maps under ideal conditions, and yet across a range of challenging environments the synergistic usage of optical and SAR data delivers more accurate and consistent outputs.
