This is the first of three tutorials that will cover ways to manipulate Ordnance Survey data using Rhino, Grasshopper & Illustrator to achieve a specific aesthetic outcome. In contrast to the prior tutorials I have uploaded, I have attempted to record these in such a way to act as a step-by-step guide for those who are interested. The later tutorials will incorporate VRay & Photoshop, as I explore additional options. Also, apologies for the typing + clicking sounds during the tutorial. I’ve used Audition to minimise them as much as possible, but I have a loud keyboard, and I need to get a better microphone setup.
