First my wife had a fall now a family member is ill, so despite all my hopes for progress over this long May weekend … it hasn’t happened. However, since my last post, I have been up to Donegal and I have taken a load of measurements. I drew the roughest of sketch maps and began slowly to measure and annotate the map.
I saw a tip in the book by Aranya, referenced in a previous post, whereby I tied knots, every 5 metres, along a long piece of white washing line (string would do). Then a pocket tape was used for the final metre or two. It’s not exact, but I don’t really need exact, do I? It’s brilliant and saves a lot of walking to and fro. A student friend has my unlovely rough work and is attempting the difficult task of transferring it to a CAD drawing. As soon as I have his draft, I’ll scan both and let you see what I’ve done.
You pick out points around the property and triangulate from those points, so that when you have a long distance to measure, you break that into smaller points and measure triangles. If you know the length of the 3 sides, your shape will be perfect as long as you stick to scale. If there are no convenient landmarks to measure from, create your own with a stake here and a pipe there and a rock someplace else. It works really well.
Another apology though, again I went without my camera. Sorry. I WILL get photos and show how I used the line and the tape. Very effective, as long as you’re careful in your counting. You also discover, as I did, that what looks like a rectangular field, is definitely not. so, again, with little real progress to show, I catch you next time.
