Mutli-sensor satellite approach used for flood mapping

Optical and radar data from Sentinel-1, Sentinel-2 and Landsat of the hydrological year 2016/2017 have been used to derive a high-resolution flood frequency map for the entire Mekong Delta.

Spatial and temporal resolution of such a map was not available to date.
