Running a line between two end points that are equally offset from the
corners should work fine. Just measure back the offset amount
anywhere along the line to get the actual boundary. I have done it a
number of times and come within a couple of inches of where subsequent
surveys showed the boundary to be.
As a matter of fact, it does need a clear shot. The signal from the
GPS satellites is not very strong, and leaves on trees is often enough
to disrupt communication with a GPS receiver. Heck, even satellite TV
dishes have trouble with leaves between them and the satellites they
Run a line parallel to the existing markers but outside the wooded
area. Then from any point you like on the reference line, measure
perpendicular into the woods the same length as the offset of the
outside line from the end markers.
Aha - yes, that's a good plan. There are really too many buildings on our
side of the line to do that, but I can do it from the vacant plot (the
folk who own it currently are good enough that I know they won't mind)
Since the lot next door isn't wooded, that's your solution.
I once worked for a survey company for a few days (a long time ago) and my
job was to cut "sight lines" through a wooded lot that was going to be
surveyed. It was no fun -- mostly just hacking away brush and small trees
to be able to see from one end of the lot to the other. It involved
multiple sight lines because the survey had to also show the elevation of
the land on the interior section. I guess there were no other magic tricks
the surveyor could do so he had to pay us to chop sight lines all day long
for a few days. We were doing it in the middle of a hot summer.
If you do end up having to chop any sight lines, it will be a lot easier if
you can wait until winter after all of the leaves have fallen off the trees.
Well, the wooded area does extend maybe 100' into the next-door lot, but
that's not too bad I think. I suspect if I do that to get my line close
(it might wobble a bit) I can straighten it up once it's 'drawn'.
Uh huh. Of course if I were to put a fence through I'd need to do
some chopping anyway :-) But I'll hold off on the fence as it depends who
buys the lot (which may end up being us anyway) and it seems a shame to
clear a path if it's not needed. Our dogs sometimes wander onto that lot
though which is the only reason I might decide to fence it.

That's what I did. A straight line from one marker to the other was
blocked by trees between the two, so I measured ten feet away from the
each marker into my property and stuck a temporary stake into the ground
at each point, then strung a line from one new stake to the other (300
feet away). I could then mark off divisions in the property line along
its length by measuring ten feet from the new line to the actual
I did a fairly good job finding my lines using an "engineers compass"
and a plot plan. The "engineers compass" is like a tiny cheap hand held
version of a transit, but worse, it came from WalMart. Very very basic.
Wait for all the leaves to fall. I went to the one and only corner
marker I could find and using the compass turned the plat map so North
is North. Aimed the compass site using the compass markings and lining
it up with the line on my map. Sighted through a tiny lens and a single
cross hair as far as the next tree it hit. Walked to that tree and did
it again. Kept doing that until I found the other corner markers, and
in 600 or so feet I was off by 6 feet. Sure that's a lot for some
things but I just wanted an idea of were the corner of my property was,
and there it was, well marked.
Turns out the other land owner had some pro's come through a couple
months later. He showed me one place I had marked, about half way
between corners, I was off by only 6 inches there and he acted like that
was a lot. Only reason I ended up 6 feet off in the end was due to the
terrain. A lot of it was literally stretching and climbing up the
mountain a couple feet at a time and getting myself on the uphill side
of the next tree to rest against. I accidentally rode down the mountain
on my ass with a shit load of leaves under me and in front of my feet.
It was kind of fun.
As far as markers, they use an ax and take off the topmost part of the
bark, it didn't get down to fresh wood. Then those spots were painted
blue. Some with 4 blue lines like a square, some just 1 or 2 marks.
I'm guessing the marks meant something that had to do with were the
exact property line was... in front or in back of the tree.
There was one spot where I am close to the property line and they marked
it with the 4 blue marks and a small yellow no trespassing sign in the
middle. It seemed to stick out like a sore thumb and from the driveway
it drew your attention. So I mixed up some mud, real mud, dirt and
water, and plastered over the blue marks. And I got a few large leaves
to stick on the nail holding the little sign. Now I don't see it, but
it's still easy to find if you are close and looking for it.
How tall is the tallest tree between the markers?
The products shown here range from 18 feet (Sale Price: $6,050) to 41
feet (Sale Price: $28,315).
Buy 2 that are just higher than the tallest existing tree, tie a
string to the top of each one and stand them up right next to the
We were trained how to do something like that with a compass during basic
training many years ago.
Perhaps you can find a new soldier who has recently had that training to
help with your project.
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
I doubt this is workable, but it's fun to imagine.
Clear a path using a machete to remove brush and small limbs even small
trees. Hopefully you will be able to see through. If not offsetting a
small amount to the side will sometimes allow you to see. Put something on
the far end that is large and highly visible.
Your county tax assessor has a high def overhead (satellite) photograph of
your property, with the survey points marked. As government property it is
available to the public. If the photo was taken when the ground was visible
beneath the trees you may be able pick out enough points along the property
line to get a rather precise set of ground points.
It's possible that you can locate the corners yourself by zooming in on
Google maps -- I just checked it out and can on my house -- even though
there are a lot of trees blocking the view I can still pick out enough
landmarks to be able to draw a property line.
Interesting - didn't know that, and I think I'd quite like to get a copy
anyway (whether it's useful or not), particularly if it's something that
might be a few years old (we're on the central lot of what was once a
farm, so have lots of farm buildings - but there were various ones that
were pulled down before we moved in, so it'd be interesting to see an
overhead view of the place before that happened)
I guess as the boundaries don't change they don't retake photos that
No joy there unfortunately - we're pretty much out in the wilds so it's an
area where they haven't done high-res data yet. I'm kind of hoping they
don't until after I re-roof the barn, then I can leave them a nice message
on the top ;)
I looked up some directions the other day on Google. I normally use
mapquest, so Google dir. was new to me. I clicked on one of the camera
icons, out of curiosity, and....lo and behold...there I was, the day I
worked on putting some Bondo on the old Buick in front of the house :o)
