Datasets description

This dataset adopts the surveying and mapping results of ALOS satellite, and undergoes image stitching, projection transformation, cropping, and other processing to generate a 12.5 m resolution digital elevation model (DEM) for Gansu Province. The data can provide basic geographic data support for regional scientific research in Gansu Province
