渭河流域水文因子数据集

所采用的数据源为DEM，从地理空间数据云（http://www.gscloud.cn/search）下载，对多幅DEM进行拼接，利用渭河流域的矢量边界对DEM进行裁剪，最终得到渭河流域DEM数据。通过水文分析可确定河流方向、提取河网、河网分级、提取流域，主要包括以下5部分： &...

The data source employed is DEM, which was downloaded from the Geospatial Data Cloud (http://www.gscloud.cn/search). Multiple DEM tiles were mosaicked, then clipped using the vector boundary of the Wei River Basin, and the DEM data of the Wei River Basin was finally obtained. Hydrological analysis was conducted to determine river flow direction, extract river networks, perform river network classification, and delineate watersheds, which mainly includes the following 5 parts: &...
