%X On July 25, 2012, lidar aerial remote sensing flight test was carried out in hulugou observation area in the middle and upper reaches of Heihe River by using Yun 12 aircraft and als70 produced by Leica company. The als70 laser has a wavelength of 1064nm and multiple echoes (1, 2, 3 and last) Hulugou area is divided into two flying areas with different altitudes. The absolute altitude is 4800 and 5500 meters, and the average point cloud density is 1 point / m2. Through the steps of parameter calibration, automatic classification of point cloud and manual editing, DSM and DEM data products are finally formed
