I developed a technique last year during the Keyline Design Course at Tuscon, Arizona for making a contour map using cheap available materials. One of our students didn’t have the cash to get a surveyor to do the job on his 40 acres, so I came up with this solution on the whiteboard and have since tested it on the ground quite a few times now.
