| * ``slope`` controls the height threshold at each iteration. A slope of ``1.0`` | |
| represents a 1:1 or 45º. | |
| * ``initial_distance`` is _intended_ to be set to account for z noise, so for a | |
| flat surface if you have an uncertainty of around 15 cm, you set | |
| ``initial_distance`` large enough to not exclude these points from the ground. |

Hello,
I watched this nice video on how to download LiDAR from the USGS Earth Explorer.
But then I saw the moment that the files were downloaded and I was initially shocked to see that the LAZ file was hardly smaller than the winzipped LAS file. So I decided to investigate by following the steps in the video to download the exact same tile (see attached picture series).
