Abstract
As an important ecological barrier in China, the Yellow River Basin is characterized by fragile ecological environment and serious soil erosion. The hydrological analysis plays an important role in soil and water conservation and ecological environment protection in this area. This dataset contains four factors for hydrological analysis, namely flow direction, flow length and stream network. The data are sourced from the ALOS 12.5 m DEMs, which were then processed through preprocessing, framing, projection, mosaic and hydrological analysis and calculation. Compared with data products of the same.
