We used a CNC (Computer Numerically Controlled) milling machine to build the 3D Map from geospatial data of the Jurassic Coast supplied by Dr Andy Ford of Bournemouth University. By starting with a solid block and removing material, the Subtractive Rapid Prototyping (SRP) solution provided an excellent result with fine detail.

Vertical scale exaggeration was necessary when modelling the coastal terrain. An exaggeration of 20% was used to create the relief required for a 3D map.

The next stage would involve hand-painting the model from satellite images of the coast.
