Derived Hydrography of Africa

This resource includes three hydrographic geospatial datasets for Africa 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.

本资源包含非洲地区的三个水文地理空间数据集，包括河流、流域和盆地面积。这些数据集由布里格姆扬大学开发，利用ArcGIS标准地形分析工具从Esri提供的数字高程模型数据中提取特征。数据集的创建旨在支持GEOGLOWS（http://www.geoglows.org）预测，采用ECMWF（https://www.ecmwf.int）集合天气/水文模型以及RAPID河流路由模型（http://rapid-hub.org）。这些数据集免费提供给公众使用，任何用途均可免费使用。若您使用这些数据，请参照HydroShare着陆页底部“如何引用”中提供的信息引用本水文共享资源。
