This data uses SRTM 30-meter resolution DEM data as the data source, performs image processing such as data splicing and resampling, and then utilizes the Weihe River Basin regional boundary cropping to generate the Weihe River Basin regional DEM data product with a spatial resolution of 30m.
This data can provide basic geographic data support for scientific research in the Weihe River Basin region.

The 30 m resolution DEM data for the Weihe River Basin are from NASA's SRTM v41 1s data, which is currently distributed free of charge by the USGS and can be downloaded for free from the USGS FTP site.
The Python program was used for image stitching and resampling; cropping was performed according to the Weihe River Basin boundary for the study area, and the Weihe River Basin 30-meter DEM data products were generated.
The source data were resampled and the data quality is good. the vertical error of the SRTM DEM data is less than 16 m. The data were resampled and the data quality was good.
