NYC performed a LIDAR scan of NYC in conjunction with CUNY a few years ago so that they could build a 'solar map' to help estimate how much solar capacity could be installed on a building. Anyone know where to grab the LIDAR scan data from?

#23That's really cool. Wish it was printed in colour :) If LIDAR data isn't available, you can do pretty detailed 3D mapping with a regular camera and UAV, using photogrammetry/structure from motion. A Phantom or almost anything that flies with a reasonable camera will do. Of course the better camera you use, the better the results. Flight restrictions over populated areas apply, check your local legislation :) commerci…
Color 3D printing is pretty pricey still. For something of that scale you'd be looking at several thousand dollars, even breaking it down into small individual pieces.

#25How about printing a landscape from a map/contour lines? Do you think it is possible for example from OSM data? (That London looks totally cool.)
I'll plug an open source lib I wrote called shp2stl that converts shapefiles into 3D models suitable for printing.

It's not exactly contour lines, but I made a site [0] that creates STL files from a global digital elevation model. You can select a region of the Earth and get a 3D printable file of its terrain. Might be close to what you're looking for!

You could shine a laser projector on it to color it!

#28Awesome, is there any data like this for SF / bay area?
Yes, from the SF city open data portal:
https://data.sfgov.org/Geographic-Locations-and-Boundaries/B...?
We're working on importing this data into OpenStreetMap:

#29That is very cool! Have you thought about tiling along road /river edges to hide the seams?

#30Does anyone know where to get Lidar or other 3D Data from Germany? (Especially Frankfurt?)
