Fig. 1: Global flood map.
From: Mapping global floods with 10 years of satellite radar data
Aggregated global flood extent map as detected by our deep learning model applied to 10 years of Sentinel-1 SAR data (October 2014–Sep 2024). Blue areas indicate locations where flooding was detected at least once during this period, shown at 250-m resolution. Darker gray areas represent the exclusion mask, indicating regions where flood detection may be unreliable due to urban development, steep terrain, or arid conditions. Areas without color showed no flooding during the observation period. This map highlights historically flood-prone regions identified by cloud-penetrating SAR data.
