TY - Data T1 - SHIFT: A DEM-Based Spatial Heterogeneity Improved Mapping of Global Geomorphic Floodplains A1 - Lin Peirong DO - 10.5281/zenodo.11835133 PY - 2024 DA - 2024-12-27 PB - National Cryosphere Desert Data Center AB - 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 DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/6d981a90-4e02-4b27-8480-0097c5817261 ER -
