Dataset Information

This dataset comprises a 1-m-resolution digital elevation model (DEM) of the Sertengshan Piedmont Fault in Northern China acquired by an airborne LiDAR survey. The LiDAR data were collected by the Aerospace ShuWei Company in Beijing, China in August 2019, using a Riegl VUX-1LR airborne LiDAR system mounted on a DM-150W fixed-wing unmanned aerial vehicle (UAV). The LiDAR data cover about a 1-km-wide swath along ~185 km section of the Sertengshan Piedmont Fault. The average point density is higher than 4 points/m2 and as high as 10 points/m2 in some local areas. The vertical accuracy of the LiDAR data is demonstrated to be better than 10 cm.
