Release of the updated potentially-affected population layer in GFM
A new version of the GFM (Global Flood Monitoring) product output layer Affected Population, which estimates population potentially impacted by floods, has been released on March 22th 2023.
In this improved GFM product output layer, the affected population is computed for each pixel by combining the observed flood extent detected by the GFM product with the Global Human Settlement Layer (GHSL) data, in particular the GHS-POP dataset, which represents the population's distribution and density as the number of people living within each grid-cell.
In this latest release of the GFM output layer Affected Population, the new GHS-POP dataset at the highest possible resolution (100m) and for the latest available time-step (2020) is now used, replacing the former GHSL population dataset at 250m resolution with the reference year 2015, which was available at the start of GFM operations and has been used during production from October 2021 to February 2023
