I developed a technique in 2007 during a 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.
Using a Bunyip/Water Level, A Frame, Laser Level or Dumpy/Automatic Level mark out a contour line using stakes or pin markers (see below for an alternative to this technique in some circumstances).
