Gps Help Coordinates

[mknolls]

I'm trying to locate all corners of my 40 acres. I have One marker for sure. Would like to know how to calculate 1320 feet from that marker to locate the other three corners convert it to a GPS coordinate so I can find it. Is there a way to do so? Any advice would be help full.

Thanks

Yes

What make and model handheld gps do you own?

Unless you want the mathematical equation to figure it out?

You should use the UTM coordinate system. The disadvantage of traditional degree minute second coordinates is the distance between 1 degree east to west varies in relation to the poles and equator since the earth is round. It's still doable, but requires a little more math.

To use the UTM coordinates convert 1320 feet to meters (402.336 meters). Set your gps to UTM coordinate system. Go to the known corner. The GPS will show your position as ####### East/West, and ######North/South. Assuming you know the northwest corner you would subract 402.336 meters to find the SW corner. Repeat for the other two. I'd find the SW and NE off the known and the SE off both of the SW and NE.

After a little more thought, this may be more valuable.

Otherwise contact the Wright County Surveyor and they can help you out.

That works if it is a "perfect" forty which often is not the case. The distance does not have to be exactly 1320 feet and the direction does have to be exact cardinal directions. This is it costs so much to have a forty surveyed.

If close is good enough than this will probably work.

Are coordinates from Google Earth accurate enough for your needs?

Borrow a metal detector. The stakes from when it was surveyed the last time should still be there. Most commonly they were lengths of rebar.

If it was never really surveyed, then never mind, although you said you found one corner.
