[closed] 3D printing tactile maps

I wish to enable printing tactile maps for blind people, using mostly likely a 3D printer.

The initial goal is to produce maps that are suitable for pedestrian navigation, and so cover an area from a few hundred meters to some two kilometers across. The solution should be easily usable by the blind people themselves, thus will eventually include an accessible web site that produces files ready for 3D printing, and no manual customization of the map contents should be needed.

The easiest implementation appears to be to extend OSM2World. The required changes are at least:

• Raise roads – this alone goes a long way to enabling pedestrian navigation
• Add a cube underneath the map for physical support
• Clip objects that extend outside the selected map area

My question is: does it make sense to extend OSM2World, or should I look into some other pieces of the OpenStreetMap ecosystem?
