I had my local canvas worker make four with eyelets in each corner to peg them down. Had them numbered 1-4 . Cost about $180 Aust and that's about the same Canadian.Does anyone have a new or as good as new set of black on white 24" ground control points they dont use? In Alberta if possibel.
Buy anything specifically called "GCP points" and you'll pay specialist prices for something you can make yourself. Try this idea. It works just as well.
Felix, that is a GREAT IDEA
