Derived Hydrography of North America

This resource includes three hydrographic geospatial datasets for North America 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.

本资源包含三套面向北美地区的水文地理空间数据集，涵盖水系、流域与盆地区域。本数据集由杨百翰大学（Brigham Young University）研发，依托ArcGIS内置的标准地形分析工具，从Esri提供的数字高程模型（Digital Elevation Model）数据中提取相关地理要素。本数据集的研发初衷是支撑GEOGLOWS（http://www.geoglows.org）的预报工作，其采用了ECMWF（欧洲中期天气预报中心，https://www.ecmwf.int）的集合数值天气/水文模型，以及RAPID河道汇流模型（http://rapid-hub.org）。本数据集可免费用于任何用途。若您使用本数据集，请依据本HydroShare资源首页底部的“引用方式（How to Cite）”板块中的相关信息，对本资源进行引用标注。
