The only thing comes to mind to me. Use a high power laser,
and burn through the trees and leaves. There should be
enough visible burn damage to follow with the string.

No, I don't have a high power laser listed on Ebay for such
a purpose.

I doubt this is workable, but it's fun to imagine.

We've got a bunch of woodland that's partly on our property
and partly on
a neighboring (vacant) plot. Runs for about 300' or so, and
there's a
boundary marker either side of the woods.

I'd quite like to add a few more markers within the trees,
just so we know
where the boundary is (and maybe fence at a later date) -
question is, how
to mark it out? The woodland's too dense to see through to
the other side,
even at night with a flashlight on one of the markers, so I
can't just
walk and "home in" on it.

I'm not sure that GPS is accurate enough to do it that way -
any other
clever tricks?

Did wonder about running two lines, meeting at one of the
markers. All I
need to do is get them straight through the trees (which
might be a
challenge in itself) - then I can presumably measure
distance from each
to the other marker at the far end, translate that to a
scrap of paper,
and calculate where the "true line" is between the two
markers for any
given distance along one of my guide lines. Does that make
sense? Maybe
there's a simpler way, though...

Ideas on a postcard, or on usenet, whichever is easier.

cheers
