If I have a deed that doesn't close by 0.76' I'm a sorry surveyor if I can't find existing corner monuments.?ÿ I must have forgot my magnetic locator and my shovel.
Some of you guys are not fully wound.
It's just a tool. I'd prefer to NOT throw it into the last leg. That's the one answer, that we know isn't.
It's so as to look for larger than expected anomalies, while searching. It speeds my processing, and flags me about particular points. While in the field. By reducing my expected ellipse size, to start with. Some mons are disturbed, some are gone.

Just a tool. At 5 to me this was much more than a tool.
Trick question. How best to distribute the error.
Show a tie to the 'true corner' at your calculated position on every found bit of corner evidence with a bearing to the nearest second and distance rounded to the nearest .001', based on the superiority of JAVAD over the original compass and short chain used and your ability to massage the original numbers from a pig's ear into a silk purse.?ÿ
Or just evenly proportion the error throughout all the legs and force it to close. The original corners were wrong anyway.
(Tongue in cheek) wink, wink.

Just because I'm paranoid, doesn't mean they aren't out to get me.
I personally don??t like tweaking deed angles in a mosaic to force a closure. I??d rather just leave the misclosure hanging open in my mosaic, look for some corners, and THEN decide what to do.
I typically do my own drafting before signing and sealing, but occasionally I??ll pick up a mosaic from a tech and resolve the boundary. And I swear, every time, they have a mosaic full of pretty ??closed? deeds, where the original geometry is no longer intact.

What do you do when you get a line where there??s no corner or other reliable evidence to hold? You may end up holding the interior deed angle and distance off the previous line. And what angle are you going to hold? The one specifically called for in the deed or one you may have made up?
But the deed doesn't actually misclose. He is just trying to add precision. There is no error to proportion. The deed actually closes, and the higher precision "misclisure" is an insignificant 0.75
original geometry is no longer intact.
No. The "original geometry" was "no longer intact", after the rounding. Rounding destroyed the original geometry. I'm "putting it back". Remember, throwing it into the last course, only for SURE puts it back, where it "doesn't go".
Really, are we having this discussion??ÿ
How much does * net cost, and where can I buy it?
It's an efficiency tool. Tools are good, if you know what they do, and don't do.
Rtk GPS is not as accurate as a box tape and calibrated compass, for a move of 0.10'.?ÿ
But, it is also non cumulative.
Know thy tools.

throwing it into the last course
Any course could be the last course. The POB is/was an arbitrary choice among the corners.
What do you do when you get a line where there??s no corner or other reliable evidence to hold? You may end up holding the interior deed angle and distance off the previous line. And what angle are you going to hold? The one specifically called for in the deed or one you may have made up?
I'll play, but I'm just low level guy still...
Are we talking a corner, or " A Corner," because I'm inclined to think that if there's no evidence left or accessories or reliable anything, with "A Corner" I'm looking at rehabilitation and the work to do that, but if it's just a corner, I'm going to be creative and figure out how to best recreate and locate and replace it based on my states statutes to the degree that requirements of the standard of practice is being adhered to etc.?ÿ Although I only get the neck down work currently, but I'm working my way up the hill to get to work in the head shed too eventually.
I only got 4 hours or less sleep. that's my excuse.
carry on.

If the deed provides a description and there are no record surveys to be found, you become the first surveyor, in a sense.?ÿ The description may have been fabricated by drawing lines on a USGS topo map, measuring them with a typical ruler and angles guessed at by using a grade-schooler's plastic compass.?ÿ I am certain that is what I am following on a current job as I am certain an attorney I know well created the description.
You can take that description, search for control points per those words, and stop and throw up your hands and say, "This is impossible."?ÿ On the other hand, you can arrive at your best estimate as to what was intended and declare you have a solution that can be debated by others over the next millennium.?ÿ The tools to arrive at that best estimate are completely dependent on you.?ÿ Software, such as Starnet, is an option.
In my specific case, I am constrained bya section line,?ÿ a quarter-quarter section line and a railroad right-of-way.?ÿ The only number being held as fixed is the length along the QQSL.?ÿ That also is representative of possession.?ÿ The distances provided to the railroad right-of-way are not expected to be accurate, especially due to the curvature of the tracks.?ÿ In fact, they are incorrect by about 30 feet.?ÿ But, the "to the westerly right-of-way line" is the critical controlling call.?ÿ The measurement given in the deed is irrelevant.

OK, I stand corrected...

Nate
I, too, stand corrected.?ÿ A protractor is precisely what was intended.?ÿ Thanks, Bill.?ÿ Don't let me fall off the cliff.
The real question is, "Is the error all in one place, or pretty evenly distributed?"
And, when we "Re distribute it" do we do it via compass rule, or the "Rounding Rule" of adjustment? I am wanting a "Rounding Rule" Adjustment, cause that is what happened.
Words. Just words, I am using words. My words are just different than yours.

Rounded numbers? Probably not if they are old deeds. Older surveying used instruments with lower precision output compared to today?ÿ
I see a future where closing to the hundredth is considered too rough. Surveyors are measuring to the thousandth now. And hundredths of a second.?ÿ Does that seem absurd to you? Well, measurements to the hundredth and to the second seemed just as absurd to the surveyors of 50 years ago.?ÿ?ÿ
We??re looking at a long time before there will be positional tolerance standards for boundary surveys that will require that accuracy. ?ÿI can see the pin cushions and map notes now.
Nobody is going to apply that standard of care unless they are very well compensated.
R. Leonard is probably one of the few people willing to pay for it.
Nobody is going to apply that standard of care unless they are very well compensated.
That is what they said around here in 1851 about accuracy to better than a tenth of a chain, in 1900 about surveying to better than a foot, in 1950 about a tenth of a foot, and in 2000 about a hundredth.?ÿ Time marches on.
