Does anyone have any tricks and/or tips for measuring the ground distance
of a meandering trail on a map? There are "map wheels" one can buy, very
similar to the distance measuring wheels used in the real world (a bit
smaller though!) yet these seem to be fairly clumsy to use on a tight,
I am thinking if I tape the map to the wall and then insert little map pins at
every turn in the trail, then I can string a string along the pins and
measure the string. Before I actually do this and put a zillion little holes in
my maps, I though I'd ask if there was something simpler.
I do not care about the errors induced by the curvature of the Earth, or
elevation gain and loss, but I do want something better than measuring
the straight-line distance and then saying it's longer than that. A target of
+/- 10% would be a good place to start.
