All one has to do is follow one’s own survey to find out one is not repeatable on the 2 or 3 hundredth level.
And there’s a difference between the perfect numbers on a plat that closes everywhere and the monuments that get set.
One thing that has upped our accuracy for set monuments is the Dewalt and the Hilti. Those tools are only partly for convenience and avoiding injury. They also help accurately set the monument compared with beating them in using hammers.Â
But still, we all add errors when we survey. Limiting them is the key, eliminating them is impossible.Â

hell I’m working on a plat from 1924 and all the distances to the 10th and all the directions are only to the minute.
I’d like to see how they handle that deal.
Â
…they would add the zero to the end of the dimension and two zeros for seconds, then everything not perfect would be a MAJOR error in their book…
My $0.02 about expert measurers (slightly jaded opinion against those that call themselves surveyors and pull s%#t like not honoring a monument that is less than 0.50′ from their calculated monument) rant for the morning is over (for now)…..
Â
to be honest, I did find a few hundredth lines, and yeah, the 01 seconds to 59 seconds for 1200′ runs would never close.
they didnt close either way and field work has provided a few poorly located monuments and will require a wider area of analysis to tie down what I need to provide the big boss the confidence in the drawings and exhibits.
great to work from the range I get exposed to and educated by.

Or what are his equipment and centering standard errors.  Let them dig into the equipment manuals and weighted least squares adjustment theory.Â
He needs to ask them what their secret is to producing completely error free measurements.Â

I have been off the forum board for a long time, bless me father (Wendell), but we have been looking for the answer for that 0.04 since Bob Plumb and Mark Deal started forum boards.  Glad to hear it is still a mystery LoL.  I remember a thread of Trimble Man’s (Derral) that probably had more posts than any thread.  The mystery and saga continue. Â

@northernsurveyor Good to see you back. Darn shame about the Shell Lake Lodge burning down.
 It is a shame, hard to look across the lake and see nothing there or activity. Â

Where is that 0.04′?
The freeze thaw moved it.
The tectonic plates moved.
Maybe a black bear found that rebar, and needed to scratch his / her nether regions.
A tree musta fallen on it.
There were signs that a cow in labor, snuck off, bedded down by it. She moved it via labor pains.
Are you kidding? Here we are, on this planet, flying through space at 10,000 mph, and that 0.04′ is going to escalate your blood pressure?
At 10,000 mph, do you realize how many feet we move every 1/2 second? And you are worried over 0.04′?
So, it’s 0.04′ off? What direction?
Say, when’s full moon?

Just wait till we start chasing coordinates with the new 2022.Â
