Data source description

  The 90 m resolution DEM data for the Weihe River Basin are from NASA's SRTM v41 3s data, which is currently distributed free of charge by the USGS and can be downloaded for free from the USGS FTP site.

Data processing method

 Using the Python program, the SRTM v41 3s binned data were formatted, spliced, and cropped to obtain 90 m resolution DEM data extracted according to the Weihe River Basin regional mask.

Data quality description

  The vertical error of the SRTM DEM data is less than 16 m. The data quality is good.
