资源简介:
2012年8月25日,在黑河中上游的核心观测区域,利用运12飞机,搭载Leica公司ALS70,开展了lidar航空遥感飞行试验。ALS70激光波长为1064纳米,多次回波(1,2,3和末次)。样带飞行绝对航高5200米,平均点云密度1点/平方米。通过参数检校、点云自动分类和人工编辑等步骤,最终形成DEM和DSM数据产品。
On August 25, 2012, a lidar aerial remote sensing flight test was conducted in the core observation area of the middle and upper reaches of the Heihe River using a Y-12 aircraft equipped with Leica ALS70. The ALS70 has a laser wavelength of 1064 nm, and supports multiple echoes (1st, 2nd, 3rd, and last echo). The absolute flight altitude during the transect flight was 5200 meters, with an average point cloud density of 1 point per square meter. Through procedures such as parameter calibration, automatic point cloud classification and manual editing, the final DEM and DSM data products were generated.
