The GFPLAIN250m includes raster data of Earth's floodplains identified using a geomorphic approach presented in Nardi et al. (2006, 2018). The 250m floodplain dataset is derived by processing the NASA SRTM Digital Elevation model gathered from http://srtm.csi.cgiar.org/, and in particular the 250-m SRTM version 4.1 DTM. Files are stored using both the Esri ASCII raster and the GeoTIFF Format and provided as seamless dataset using the World Geodetic System 1984 (WGS84) datum and geographic coordinate system. Floodplain raster layers are compressed into a single file zipped for each continent including the corresponding ASCII file. The coding used for each continent and additional information are detailed in the metadata included in the GFPLAIN250m data repository.
