Schoharie Valley 3d map
by chrisniederer, published
Created using a free program called Maperitive, which downloads elevation data from the open street map project. I then import the models into sketchup and do some post processing in meshlab and netfabb.
As shown printed in ABS and painted by my friend Alex.

Re: Damm31, I import the dae file from maperitive to sketchup, scale it, use the free stl exporter plugin, to export to stl, then usually refine the mesh and then take it back into sketchup to add the base and make it watertight, sometimes I scale it or check for watertightness in netfabb. Some geography seems to be better quality than other areas, so sometimes it works better than others. Also, sketchup will balk at handling too many faces, so large areas of terrain can be difficult and slow.
Take a look at the mesh image above that is just a surface, that is from sketchup after I scaled it, exported it, then did a quadratic edge collapse filter in meshlab and then brought it back into sketchup. Shown is the step before adding the base to it.
Hope that helps...
can you share some more details on the processing flow and commands you used? I tried it, but when I export from Maperitive 2.3.21 ("Export to 3D") and import the resulting .dae file in Meshlab 1.3.2 ("Import Mesh"), I get a warning that the mesh would contain 0 vertices with NAN coords and <nnn> degenerated faces.</nnn>
