确定洪泛区边界对于解决河流风险和资源管理的地球，环境和社会经济研究至关重要。然而，到目前为止，还没有建立一个全球洪泛区划定使用均匀的程序。在本文中，我们提出了第一个，全面的，高分辨率的，网格化的数据集，地球的洪泛区在250米的分辨率（GFPLAIN250米）。我们使用航天飞机雷达地形使命（SRTM）数字地形模型和地形分析程序的地貌洪泛区划定。高程数据由一个用于洪泛区制图的快速地理空间工具处理，该工具可在https://github.com/fnardi/GFPLAIN下载。GFPLAIN 250 m数据集可以支持许多应用，包括洪水灾害测绘、栖息地恢复、发展研究和人与洪水相互作用分析。为了测试GFPLAIN 250米数据集，我们进行了一致性分析，来自欧洲的洪水灾害建模研究的洪泛区划定。
Identifying floodplain boundaries is of paramount importance for earth, environmental and socioeconomic studies addressing riverine risk and resource management. However, to date, a global floodplain delineation using a homogeneous procedure has not been constructed. In this paper, we present the first, comprehensive, high-resolution, gridded dataset of Earth's floodplains at 250-m resolution (GFPLAIN250m). We use the Shuttle Radar Topography Mission (SRTM) digital terrain model and set of terrain analysis procedures for geomorphic floodplain delineations. The elevation data are processed by a fast geospatial tool for floodplain mapping available for download at https://github.com/fnardi/GFPLAIN. The GFPLAIN250m dataset can support many applications, including flood hazard mapping, habitat restoration, development studies, and the analysis of human-flood interactions. To test the GFPLAIN250m dataset, we perform a consistency analysis with floodplain delineations derived by flood hazard modelling studies in Europe.
