I want a photo of a print :)

fantastic! anyone have sources for USA lidar point clouds? In related projects, this script takes a GeoTIFF (which usually comes from a lidar pass) Digital Elevation Model, and renders it inside minetest (opensource voxel game). https://github.com/Gael-de-Sailly/geo-mapgen#readme https://github.com/Gael-de-Sailly/geo-mapgen#readme

  The National Map! https://viewer.nationalmap.gov/basic/ https://viewer.nationalmap.gov/basic/ Kinda hard to use, though. You can find the raw data by state here: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/NED/LPC/projects/

This looks very nice! I've been toying with open LIDAR data from my country (0.5-1 points per m^2) in MeshLab but always got very noisy/spiky meshes.

  There are a few solutions much better than the old tech used by meshlab. Specifically, fssr[0], which does a more advanced and especially sample-density-compensating variant of meshlab's poisson reconstruction, as well as instant meshes[1], which does generic retopo, and is able to handle point clouds, while still being _very_ fast and delivers surprisingly good low-poly results (see for yourself).

This reminds me of TerraFab (http://terrafab.bengler.no/ http://terrafab.bengler.no/). A Norwegian site where users can zoom in on norwegian fjords, and press the order 3d print button. Edit: Someone has put up the Terrainator site (https://terrainator.com/ https://terrainator.com/) that generates 3D print files from Google maps. It costs money and you have to 3d print the thing yourself.

  There’s a free version (with more options) at http://jthatch.com/Terrain2STL/ http://jthatch.com/Terrain2STL/ Haven’t printed anything yet, but the STL loads great into a slicer (I used cura) of your choice.

  Does Slartibartfast know about this!? He was quite proud of those fjords..

what's the cheapest way to get a lidar-scanning drone up and running?

  I think LIDAR equipment is still the size of a dishwasher

    Not at all, there are many very small and even solid state LIDAR scanners on the market at an accessible cost edit: Here's a review of 12 https://www.dronezon.com/learn-about-drones-quadcopters/best-lidar-sensors-for-drones-great-uses-for-lidar-sensors/ https://www.dronezon.com/learn-about-drones-quadcopters/best...
