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.
