This data was created by modifying the scripts to work with 90-m data. Global FloodPLAIN (GFPLAIN) mapping uses a geomorphic algorithm. Geomorphic FloodPLAIN mapping algorithm GFPLAIN is based on Nardi et al. (2006, 2018). The data is available at the hydrobasin 4 level. HydroBASINS data provides a series of polygon layers that depict watershed boundaries and sub-basin delineations at a global scale (http://www.hydrosheds.org). GFPlain90 floodplain data provides a series of raster datasets that depict floodplains wetlands at a global scale. Each raster represents a single hydrobasin. These 90 meter floodplains were created to help identify globally non-floodplain wetlands. Floodplains were created globally by hydrobasin. The floodplain extent resolution of 90-m was resampled to 30-m for performance assessment and overlap analyses with the wetland spatial data. The United States Environmental Protection Agency through its Office of Research and Development partially funded and collaborated in the development of this dataset under contract EP-C-15-010/68HERC20D0029 to Pegasus Technical Services. This dataset has been subjected to Agency review and approved for publication, but does not necessarily reflect the views and policies of the United States Environmental Protection Agency.
