Hi! Lots of suggestions here. But if I understand you correct it is lidar data and all about photogrammetry is not in question. Why not pdal? Open source, powerful and what QGIS is using in 3.18.

Hi Benoit, ok, thanks. las then. But when I read about the lastools plugin, the description says that I need to install the lastools software, and the website there tells me that the license is about 1500€ which is a little too much for some learning efforts. Any other options?
