FSU Jena wins the SPSG Park3D Project! Updated

First L2 LiDAR data capture over Park Sanssouci – (2025-07-20)  Priority was on detailed and dense vegetation point clouds. The L2 was used in 120m AGL with 240khz capture rate and 5-returns activated and 70% track overlap at 8m/s speed.  We generated a 2.4billion point cloud description. The following animation is from a downsampled version of only 500 mio points....
