Derived Hydrography of World Regions

This resource includes three hydrographic geospatial datasets for 13 world regions including: Rivers, Watersheds, and Basin area. These datasets were developed at Brigham Young University by using standard terrain analysis tool in ArcGIS to extract features from digital elevation model data provided by Esri. The datasets were created for the purpose of supporting GEOGLOWS (http://www.geoglows.org) forecasting using ECMWF (https://www.ecmwf.int) ensemble weather/hydrologic model and the RAPID river routing model (http://rapid-hub.org). These datasets are provided free of charge for use for any purpose. If you use these data, please reference this HydroShare resource using the information provided in \"How to Cite\" at the bottom of this HydroShare landing page.

本资源包含覆盖全球13个区域的三类水文地理空间数据集，分别为河流、流域与盆地面积数据。此类数据集由杨百翰大学（Brigham Young University）基于Esri提供的数字高程模型（digital elevation model）数据，借助ArcGIS内置的标准地形分析工具提取特征构建而成。本数据集的构建旨在支撑GEOGLOWS（http://www.geoglows.org）的预报业务，该业务依托欧洲中期天气预报中心（ECMWF，https://www.ecmwf.int）的集合式天气/水文模型与RAPID河道汇流模型（http://rapid-hub.org）实现。本数据集可免费用于任意用途。若您使用本数据集，请参照本HydroShare主页底部「引用方式」中提供的相关信息，对该HydroShare资源进行引用。
