Creating 3D buildings from OpenStreetMap data - Markus Neteler | Geospatial Analysis | Remote sensing

It is fairly easy to create 3D buildings from OpenStreetMap (OSM) maps, essentially by extruding the 2D footprint polygons to 3D.

For the procedure using OSGeo software, see

It still works!

Yes, absolutely! We maintain it like a pet :)

Pretty nice, but you should check this out :)https://wiki.openstreetmap.org/wiki/3D_Development

Once 3D buildings are extruded, is there a way to export them from Grass? I’ve tried DXF and no 3D program recognises the file type. I’ve also tried VTK but Paraview displays terrible triangulation to the building tops. Any suggestions? I’m aiming to get the city model into Blender for rendering/animation

Thanks!
