[OSM-talk-be] LiDAR

[joost schouppe]

Haven't seen it in practice, though I do have an idea whom I could ask. The
"pattern" I mean is that there is a special kind of randomness to the data:
whereas buildings tend to be high or low according to a regular geometric
form, a tree has high points (where the beam touches a high branch or leaf)
and low points (where the beam goes all the way down to the ground or a
lower branch/leaf). If you visualise the raw data, it should be quite
obvious to the human eye.
