Data source description

The 90 m resolution DEM data of Jinghe River Basin comes from the SRTM V41 3S data of NASA. The data is currently distributed free by USGS and can be downloaded free from USGS FTP site.

Data processing method

Using Python program, the SRTM V41 3S framing data is processed by format conversion, splicing and clipping, and the 90 m resolution DEM data is extracted according to the regional mask of Jinghe River Basin.

Data quality description

Good data quality.
