On July 19, 2012, airborne laser lidar data were obtained in the core test area in the middle reaches of Heihe River, which can provide surface elevation information with high spatial resolution (meter level) and high precision (20cm). DEM, DSM and point cloud density maps are generated through airborne lidar data processing. On this basis, DSM and DEM are directly subtracted to obtain the vegetation height product in the core test area in the middle reaches of Heihe River Basin, and the overall accuracy of the product is 88%.
