Governments and organisations the world over are releasing free LiDAR data - capturing the globe in 3D down to the metre. But how can you take this data and make into something tangible? And how can you do it at both the small scale of cities and the enormous scale of mountain ranges?

We'll look at three different methods of making 3D terrain models via both 3D printing and CNC machining - examining where the data comes from and LiDAR technology; the challenges of LiDAR data and how to shape it into 3D models; and how to take these highly detailed models and successfully print or machine them.
