This data contains a raster representation of the population's distribution and density as the number of people living within each grid cell. The information is available at various spatial resolutions and for different epochs.
For the GFM elaborations, the dataset at 250m resolution (highest possible resolution) and for the latest available timestep, 2015. Combining this raster data and the vectorized flood extent allows to provide the number of affected people for each specific pixel detected as flooded.
