%X On August 25, 2012, lidar aerial remote sensing flight test was carried out in the core observation area in the middle and upper reaches of Heihe River by using Yun 12 aircraft and Leica company als70. The als70 laser has a wavelength of 1064 nm and multiple echoes (1, 2, 3 and last). The absolute flight height of the transect is 5200m, and the average point cloud density is 1 point / m2. DEM and DSM data products are finally formed through the steps of parameter calibration, automatic classification of point cloud and manual editing
