    I go walk around my property. I need to be to map the property lines and corners.

    I also find useful plants along the side of the road, which I need to come back and collect at another time of year, so I need to mark these places and list them.

    I also travel to hair cut places and I need to note where they are, and what work I did or didn't do.

    Thoughts, suggestions?

    For the plants and salons, a consumer grade GPS would be perfect. For surveying though, I don't think they are accurate enough. HH

    IF you want sub 1' accuracy you have to pay for a ground base signal. I.E. (my understanding) is you pay $$$ to business (or buy your own transmitter, set it up) and you have sub 1' accuracy.
    A neighbor has it for his equipment. He pays local JD dealership and his planters, sprayers, combines etc drive themself. 3" max off. I THINK he said it was $600 for that and the 1' was $300 a yr.
    His system plants, sprays, combines without driving over any crop. (or touching steering wheel except at ends)

    Another guy does not use that $$$ signal. He bought a transmitter. Sets it up on edge of field/hooked to battery and 10 hrs exact signal. (per charge)

    Would you care to suggest a specific one? I don't have any idea.

    Wouldn't google earth/maps and/or a purchased aerial map be better for that?

    I wonder how much "surveying" you could do with a map and range finder

    Some farmers use a Differential GPS based system.

    That is, an independent transmitter is set at a particular location (lets say at a corner of a field. Then the GPS signal is is compared to the independent signal and the difference can give crop row to row accuracy.

    Surveyor GPS equipment can provide around 3mm accuracy (about 0.118 inches).

    Price is sky high for accuracy..


    Close is good enough for most stuff.

    For General GPS accuracy your positional accuracy is around - --
    My Cell phone accuracy right now is about 5/10 meters (real GPS)

    It might do better for marking property corners and stuff, but the places where I am working look like nothing but woods from overhead. On pictures I can't actually see anything.

    I believe this is accurate. For haircut places and plants something like a Garmin Nuvi will work. I have a Nuvi 260 (I think) and it has worked well for 6 years.

    For property lines you need a survey done or to just find the markers. My property lines are marked with rebar. Found it with the mower once.

    When they sold the lot next to my house it was surveyed and we discovered that my storage building was halfway on the lot being sold. I got it moved post haste!

    If you need your property surveyed, pay a surveyor, and just have it done. Much more cost effective for you.

    Then, if you're just walking your land, consumer GPS accuracy is fine for you. It's advertised as 10m accuracy for the civvie signal, but in my experience it's generally better than that.

    Garmin makes nice hand held units as well as car-mount units you can also use dismounted. Either way expect to pay a couple-few hundred bucks.

    See this below for a quick reference, and if you google you'll find lots of sites dedicated to the pro's and con's of various makes and models.

    Note that if you have/want to get a smartphone, it can do these things for you as well.

    I had to find the corners on an odd shaped parcel a while back. The land was covered in knee high grass and scattered pretty heavily with trees. It is in a remote area, so there are no streets, structures or fences to work off of. The corners were marked by short, 40+ year old rebar stakes that tended to blend into the grass and soil pretty well.

    I obtained the UTM coordinates for the corners using information on the county's webpage, and drew a simple map with the coordinates, elevations, distance between corners, and the cardinal directions marked on it. I then used an old handheld Garmin eTrex (one of the really, really, old, first generation ones). The etrex got me to within 10 or 15 feet or so of the stakes, and from there it was pretty easy to find them. On one or two of the stakes, it actually took me to within a few feet of the stakes. Once I found them, I used pvc pipe to mark them. In hindsite I didn't need to write down the elevations of the corners, but I'm anal that way...

    The eTrex also has a "waypoint" feature that lets you record the coordinates of any point you happen to be at (i.e. the location of a plant, etc.). You could copy those down into a spreadsheet for later reference.

    I believe there are all sorts of apps intended for geocaching for ipads and smartphones, and maybe you could use one of those also, particularly for listing the coordinates of locations. My iPad has a pretty wicked GPS unit in it, and I have to admit I almost never use my old eTrex except whem I'm out hunting or backpacking or somewhere I don't want to carry an iPad.

    I hope this helps. If you lived nearby, I'd be happy to help you map out your property.
