Terrain Carving CNC Tutorial by Steve M Potter

This is a detailed tutorial explaining how to get satellite terrain imagery into a 3D model, and then how to import it into CAD/CAM software and carve a topographic relief map out of wood using a CNC machine. Please see my Instructables version of this tutorial, which has additional details:

If you would like me to make a customised terrain carving for you or a loved one, you can order from my Etsy store: https://www.etsy.com/ie/listing/17682...

I am using my home-made Portable Primo MPCNC, designed by https://www.v1engineering.com/ and modified by me as described in these videos:
