Thanks for sharing! The description confused me, as it describes the use of a real Lidar measurements to detect "change" in the terrain. But certainly, it can't be a temporal change before and after... to detect medieval settings in the data. Is the area still changing differentlybetween scans over multi year's? I don't think so. I think this is visualization code highlighting natural VS. human train structures, at known locations of old settlements? Showing different approaches on how to visualize the man-made heights in the terrain. But still, I'm lost how this could help finding new ones..

I think the examples should make it more clear. Thanks to the high resolution of the data, you can see subtle changes in the slope (aka relief aka microtopography) that could hint to underlying remains of human settlements (usually some suspicious geometric patterns that you would not expect in a natural terrain).

  Here's another article about the use of such data in South America: https://www.nationalgeographic.com/history/article/maya-laser-lidar-guatemala-pacunam https://www.nationalgeographic.com/history/article/maya-lase... Of course, nothing so exciting to be discovered in Switzerland anymore ;)
