TY - Data T1 - SHIFT:A DEM BASED SPACE HETEROGENEITY IMPROVED MAPPING OF GLOBAL GEOMORPHIC FLOODPLAINS A1 - Lin Peirong DO - 10.5281/zenodo.10440609 PY - 2024 DA - 2024-05-21 PB - National Cryosphere Desert Data Center AB - This dataset is a 90 meter resolution global river floodplain landform map based on terrain analysis. This method takes MERIT Hydro as the terrain input and Floodplain Hydraulic Geometry (FHG) as the threshold scheme, using a stepwise framework that respects both power law and approximate hydrodynamic modeling spatial range to estimate scale parameters. SHIFT effectively captures the global pattern of flood plains with better regional details than existing data.This dataset provides data in two different resolutions to meet different needs. SHIFT_v1_90m: Originating from the original SHIFT data of MERIT Hydro, lakes and reservoirs have not been removed yet. In the geographic coordinate system (EPSG: 4326), the resolution is 0.0008333333333 degrees, approximately 90 meters at the equator. A pixel with a value of 1 is a floodplain, 0 is a non floodplain, and a null value of 255 (indicating that pixels below the threshold are not within any watershed).SHIFT_v1_1km: Resampled SHIFT data, marking lakes and reservoirs. In the geographic coordinate system (EPSG: 4326), the resolution is 0.008333333333333 degrees, approximately 1 kilometer at the equator. Pixels with a value of 1 are flood plains, 2 are lakes and reservoirs, 0 is non flood plains, and a null value of 255 (indicating that pixels below the threshold are not within any watershed).
