资源简介:
SHIFT是一种基于地形分析的 90 米分辨率全球地貌洪泛区地图。它以 MERIT-Hydro 为地形输入,以洪泛区水力几何(FHG)为阈值方案,通过既尊重幂律关系又拟合水动力学模型模拟洪泛区数据空间范围的逐步式框架估算水力几何参数。与现有数据相比,SHIFT 有效捕捉了洪泛区地貌的全球模式,具有更好的区域细节。
SHIFT is a 90-meter-resolution global geomorphic floodplain map based on terrain analysis. It takes MERIT-Hydro as the terrain input and adopts floodplain hydraulic geometry (FHG) as the threshold scheme, estimating hydraulic geometry parameters through a stepwise framework that respects the power-law relationship while fitting the spatial extent of floodplain data simulated by hydrodynamic models. Compared with existing datasets, SHIFT effectively captures the global patterns of floodplain geomorphology and has better regional details.
