黄河上游河流矢量图

黄河是我国第二长河，黄河泥沙问题引起全世界人民的关注。本数据根据全国1:400万河流矢量图为底图，利用黄河上游流域边界裁剪而成。河流矢量图是利用地形图提取流域边界的一个关键要素，同时也是做洪水演进和泥沙演进的关键要素。 本图以ArcGIS,.shp文件存储，包括自黄河源区到头道拐的干流和支流矢量图。河流矢量图是利...

The Yellow River is the second-longest river in China, and its sediment issues have attracted widespread global attention. This dataset is developed based on the 1:4,000,000 national-scale river vector map as the base map, and is clipped using the boundary of the upstream Yellow River basin. The river vector map is a key element for extracting basin boundaries from topographic maps, and also a critical input for flood routing and sediment routing studies. This dataset is stored in .shp format compatible with ArcGIS, covering vector maps of both main streams and tributaries from the source region of the Yellow River to Toudaoguai. The river vector map is utilized
