Indeed https://github.com/potree/potree has a bit awkward navigation, but there are quite a few nice lidar datasets available to explore with it, like the scan of the Matterhorn. I once used it to explore a dataset made by a photogrammetry drone, was quite nice.

The entire country of the Netherlands is also available here: http://ahn2.pointclouds.nl/ There is no rgb information, only elevation. But you can make out individual power powerlines, the scan resolution is really high.

AHN2 was measured between 2007 and 2012. AHN3 from 2014 to 2019 and I believe AHN4 is actually complete now (measured from 2021 to 2022?).

Better resolution, more up to date -- but I don't know of such a nice point cloud viewer for it.

Indeed, but the only viewer for ahn4 I know of is some crappy arcgis site.

This is quite amazing, thanks for these links. Do you have any more info about how was this performed? What is it used for?
