[OSM-talk] Mapping distant objects by triangulation.

[Jeffrey Martin]

I couldn't find the other thread on this topic.

How do you map an object, like a tower on top of a mountain, that
you don't have access to without expensive survey equipment?

My thought is to use a plumb bob to line up the unknown object
with some known objects. I would find something like a phone
pole between me and the mountain tower. I would move along
a road until the pole and the tower line up. Now I have a straight
line. Do it again with another strait line and I have two lines
to define the location.

Would that work?
