Super cool that it includes high(ish)-resolution buildings! Folks interested in using this data may also be interested in OpenTopography[0], which is a repository of topographical datasets (some very high resolution) with possibly more friendly licensing terms. I used some data from them to make a physical topographic map of a mountain peak. The tooling is a little opaque from a newcomer's standpoint, so I wrote up a quick howto[1]. In short you go from GeoTIFF to an STL surface with phstl, then extrude into a volume using Meshmixer (could use something else).

- dr_kiszonka 3y agoNice write-up! I wish there was a place where I could have a piece like printed _and_ painted.
- sorenjan 3y agoIf you're willing to make the textured 3D model yourself there are services that can 3D print in color. https://www.shapeways.com/materials https://www.shapeways.com/materials
- samstave 3y agoHA! I have been following your tutorial for the past couple of days. I run into a major nightmare with GDAL not being seen in python. Its installed in pip list - I have OSgeoNW, GRASS GIS etc - and no matter what I do, I cant get GDAL to work, thus the phstl conveter for mesh cant be run and I get stuck. I was inspired by that exact same user when that was posted to /r some time ago - and I went down this path then - and got just as frustrated. This is a nice tool, along with its desktop friend: https://github.com/potree/PotreeConverter https://github.com/potree/PotreeConverter
