@mightymoe same people that want dirt contours accurate to the tenth of a foot in a plowed field.

We've had the discussion here about grid is ground. First point on screen shot slide

What'll you have

In PLSS IA north used to be the section or subdivision line from which the parcel was cut out. Then GPS came along. But I digress.

Is it ridiculous to think that accuracy could be 0.01 feet based on a benchmark located 1000 feet away. I wish there were more engineers that under...

E-W is 165 + -

Also two other possibilities 1 Scaling to ground from 0,0 origin 2 international feet units

@wendell If a person is supposed to be able to sign in there using the same log in as here it doesn't work for me. Maybe I jumped the gun. I tried b...

bump it one last day.

Hey OF, You probably learned more about practical engineering on the dumb end than you realize. You are right, things have changed. While technology ...

Obviously there is a disagreement between measured and calculated of about 0.6 ft. This transformation translates and rotates about pt. 2 so that the ...

Iowa Trespass cases

Biggest surprise is its within a foot of 5280.

It appears the scale given on the county data sheets is actually the combined scale factor. So grid inverse x (1/0.9999791) = ground inverse. About 0....

I did a little high school and QCOGO exercise starting at the lower right corner and coming at the curve in the upper left from each direction using t...

You aren't missing anything. All you need to do is decide if you are going to pin cushion hell. Figure out who the original surveyor is of the statuto...

This reminds me of a problem I was asked about one time. The surveyor was taking a 400 m backsight and traversing 6 km to the next azimuth pair. They ...

picking one over another doesn't change anything for them Found three irons and a pipe at the corner. Problem solved.
