Datasets description

 The spatial distribution data of China's altitude above sea level (DEM) is sourced from the Shuttle Radar Topography Mission (SRTM) data of the US space shuttle Endeavour. This dataset is generated by resampling based on the latest SRTM V4.1 data, using WGS84 ellipsoidal projection.

Data source description

 The data comes from the Resource and Environmental Science and Data Center: https://www.resdc.cn/data.aspx?DATAID=123

Data processing method

 Using SRTM 500m resolution DEM data as the data source, perform image processing such as data stitching and resampling, and then use regional boundary cropping within Gansu Province to generate DEM data products with a spatial resolution of 500m.

Data quality description

 The data quality is good.
