A new paper on the Global Flood Monitoring (GFM) service has been released, highlighting its ability to deliver automated, near-real-time global flood maps and the creation of the first comprehensive Sentinel-1 flood archive.
The Global Flood Monitoring (GFM) service, launched in 2021 as part of Copernicus, provides automated, near-real-time flood maps for the whole world. It uses Sentinel-1 satellite data and combines three different mapping methods to accurately detect flooded areas, even under challenging conditions. GFM can deliver maps within five hours of satellite imaging and has created the first global flood archive from 2015 to today.
While it works best for large floods in temperate and tropical regions, smaller floods and areas with sparse satellite coverage, dense vegetation, or cities can be harder to map. Future improvements include using additional satellite data, better algorithms, and machine learning to make flood detection more accurate and reliable, helping communities respond faster and more effectively.
