LOVE the fact that LiDAR is OpenData!
I am currently working on a website https://hillsha.de that makes it easy to download LiDAR las/laz files for almost every place in europe, the US and some other regions. I also made an iOS app for the same use-case, which can render the LiDAR data in 3D and 2D without PDAL and GDAL. It uses a vibe-coded library instead that combines both in native Swift. The iOS app is still in testing but works great.
Implementing France was a lot more comfortable than almost every other country, very well structured metadata and naming conventions. So thanks for that
(i work at the german mapping agency but this is a private project since i just love working with LiDAR hillshades)
