Tallest tree on Chinese mainland found in Tibet(2)

The joint surveying team used drone-mounted and backpack lidar scanners to obtain the 3D point cloud models of the 11 trees potentially taller than 70 meters, and did fine surveying of their actual height, 3D structure and growing environment.

After 10 days of fieldwork, data collection and processing, the 76.8-meter pine was found. The team obtained the precise 3D point cloud data of the tree and created a full-size composite photo of the tree using images taken by drones.

Using drones to drop measure ropes and tape measure, the team verified the height and diameter at breast height of the tree and recorded the detailed data.
