how to obtain GPS coordinates?
Savers by Ceg
can enter the legal land description (township map type description) and
obtain the coordinates which can be used with GPS in order to locate the
corners of the property? Is there a website which allows this? Is this a
function of the GPS unit? Thanks for any info.

documents, but rather relative coordinated from a fixed point. The easy
way would be to go there and walk the property, recording the
coordinates at each corner, and draw yourself a map of the property. If
the area is fenced, this should be fairly easy, if not, then locating
the surveyors stakes might be quite a challenge.

Is it possible for me to go to the tax office or some other office and get
the coordinates from their section maps? Or do I have to hire a surveyor?

Hiring a surveyor can get you an opinion as much as easily seen and
agreed upon property lines. If you do that, make sure the surveyor
understands what you expect to receive and agrees to deliver that.
The starting point for the area the property is in is usually defined by
a system called Township/Range/Section or the Public Land Survey (PLS)
system. Here is a place that may help you understand that system:

You can look at the collar info on a USGS paper topo map to determine
the Township and Range. The same info can be found on the free USGS
downloads if the collars have not been trimmed off.
Reading the description for one specific property can be a little arcane
but its works okay. For example, if you have a more or less square or
rectangular property, or adjoined squares and rectangles, all with
straight lines, and there are two or more clearly defined reference
points (pins, markers, etc., sometimes called monuments) you have a good
starting point. Once the all distance measurements are right, the
property lines are right.
You can set a GPS in one place and let it average the location for days
and it will still have an error of 10 or 20 feet or more. So if you
start projecting lines from that point, that error can quickly be
compounded.
Are there monuments on the corners of the property? And is there line
of sight from corner to corner? If there is and I wanted to place
markers or a fence, I'd buy an inexpensive transit and use that to place
marks along the lines. Not having line of sight from one marker to the
next is where it starts getting complicated.

my property) has a monument at the corner. Since we both agree on that, I
asked and received a copy of his survey, The coordinates of that monument
are given in coordinates based on the NY State Plane system. After some
calculator use, these have been transformed into Lat, Long and UTM for use
with my GPSs. His survey also gives the angles of property lines (thank
goodness they are long straight lines) to other points, so posting the line
should be relatively easy. I think a RETAIL GPS can be of use in follwoing
a known property line. However, I would not depend on one, given the error
budget, to lay a propert line out in the first place.

normal latitude and longitude points, or if they have their own form of
notation.

I may be going about this the wrong way. What I have is the land
description...section, range, etc. with all the 1/4's this and that...I'm
trying to figure out if there is a way I can get obtain the corners of the
property so I can mark it out myself or if I need to hire someone to do
that. If it's a case of hiring someone, I'm not really sure who or what
department I'd need to contact.

Yellow Pages. Surveyors.

The property is in a small area called Buzzard Gap...about 5 miles out of
Wilburton, OK. It's a little spithole in the middle of nowhere. If you're
familiar with Robber's Cave Park, the property is about 10 miles south of
there.

As it turns out, GPS accuracy is not where good enough. A commercial
quality survey must by law be accurate to 0.1 foot and a high resolution
commercial survey goes down to 0.1 inch. Your typical hand held GPS,
even with WAAS, will give position "within 5 meters 95% of the time".
Using reflected laser beams is much simpler and more accurate.

numbers of active satellites. Or, it can be only 50 feet, or worse.
Good enough, perhpas, to locate old surveyor stakes, not good enough to
anchor your fence in the south 40.
