A national 3D point cloud

I was searching various forks of Potree‘s web based point cloud viewer on Github, and happen to have stumbled across a fork with a python bindings for processing huge datasets. The example given is 640billion points, and has a live search feature that is pretty damn cool. The customisable color bar is also something I’m pretty excited about, as these ideas can be used for more than just height modelling – I’m looking forward to seeing some thematic models with this in mind, with perhaps an active legend which changes with whatever level of zoom (octree) you’re on. The Netherlands, however, is pretty flat, so I may try and adapt these ideas to the UK inventory over the weekend if I have time – either way I suggest you give the webviewer a look as it’s a technical marvel if nothing else!

I’ll include 1 screen cap showing the detail at the lowest level, you can make out individual houses and trees, really impressed by it all!
