Global Flood Forecasting (GFF)

Dataset from paper: Off to new Shores: A Dataset & Benchmark for (near-)coastal Flood Inundation Forecasting

Consists of target flood maps and various inputs used to predict said flood maps. Each input modality is contained in a separate zip file. Each zip file contains a collection of raster data, one file per ROI.

Files:

• base.zip - Contains flood maps and meta-data (e.g. geolocations). Includes Kuro Siwo labels.
• s1.zip - Contains Copernicus Sentinel-1 data from 2014-2020 obtained through Alaska Foundation, using an EarthData account.
• era5.zip - Contains ERA5 and ERA5-Land data products obtained from Google Earth Engine (GEE), which was originally generated using Copernicus Climate Change Service information 2014-2020.
  
• hydroatlas.zip - Contains HydroATLAS v10 data. Rasterized and resampled to match ERA5-Land.
• hand.zip - Contains HAND data (CC0 license). Resampled to match Sentinel-1.
• dem.zip - Contains CopDEM GLO-30 data. Resampled to match Sentinel-1 and ERA5-Land.
• extras.zip - Contains 4 folders of extra data:
  • vit-snunet-extra - Flood maps, meta-data and S1 of ROIs that fell outside era5 availability.
  • vit-snunet-raw - Raw floodmaps generated by Kuro Siwo model (after removing tiling effects, before other post-processing)
  • vit - Alternate flood maps; generated using FloodViT model only
  • snunet - Alternate flood maps; generated using SNUNet model only
• worldcover.zip - Contains worldcover data (CC-BY license) resampled (nearest) to Sentinel-1. Only used at evaluation time. 

Instructions: 

1. Download whichever inputs you want to use.
2. Extract all in the same folder.
3. Point the code to that folder.

Licenses: The redistributed data products (s1, era5, hydroatlas, hand, dem and worldcover) retain their original licenses. They are, however, very permissive. Only HydroATLAS is not necessarily available for commercial use.
