Datasets description

 This data takes SRTM 30m resolution DEM data as the data source, carries out image processing such as data splicing and resampling, and then uses the regional boundary clipping of Jinghe River basin to generate the regional DEM data product of Jinghe River basin with spatial resolution of 30m.

 The data can provide basic geographic data support for regional scientific research in Jinghe River Basin.

Data source description

 The 30m resolution DEM data of Jinghe River Basin is from the SRTM V41 1s data of NASA. The data is currently distributed free by USGS and can be downloaded free from USGS FTP site.

Data processing method

 Use Python program for image mosaic and resampling; The study area is cut according to the boundary of Jinghe River Basin, and the 30m DEM data product of Jinghe River Basin is generated.

Data quality description

 Good data quality.
