%X In this dataset, based on spatially varying FHG parameters, we created a global floodplain map with a resolution of 90 meters, named "Improving Spatial Heterogeneity Floodplain through Terrain Analysis" (SHIFT). The map takes the hydrological corrected MERIT Hydro dataset as the DEM input and the height above the nearest drainage ditch (HAND) as the terrain attribute. The results indicate that the validation effect of SHIFT with reference maps is superior to that of hydrodynamic modeling methods and DEM based general parameter methods. The improved delineation mainly includes better differentiation of the main streams and tributaries of the main watershed, as well as a more comprehensive representation of the stream network that gathers the watershed
