The map shown is an apriori map built with a tilting laser scanner. The itself does build local 3D point clouds by associating laser scans with localization data.
@atotoole21 The laser scanner is indeed 2D. But it is also tilted forward, so that by moving the robot, the combined 2D slices add up to a 3D image of the environment.
@jakobmakesrobots But it looks like it scans the entire buildings and trees all the way to the top. I would understand if it were just showing a 3D model of the ground. Also, looking at the point density of the data, it looks like the data shown here was taken by a system that rotates a 2D lidar around the "roll" axis.
Cool. Good mobility. Check out my Giant Killer Robot. Yes they are finally here.

how is the laser scanner data in 3D, the robot doesn't appear to move the lidar. I would think it would only be 2D
