@antcrook There is your answer. You have to go with the mapcheck area. Like John said the difference is not likely significant. If it seems to be y...

You are thinking in terms of a traditional chain traverse. This may be a case where he side tied a boundary mark from one control that was very close,...

Possibly a misunderstanding. Also, a few states have elected to go with fairly large zones that don't really qualify as LDPs.

In Oregon, friends don't let friends work in State Plane. OCRS is the way to go. When 2022 finally hits the streets just about everyone in the US will...

@jim-frame I’m not claiming to have it perfected on that time. Just a first pass.

I believe that the practice is an artifact of the days before GPS. Back then you wanted some way to determine a basis of bearings. One could do a sun...

@lurker Presumably each group would be assigned point number ranges to work with. So you would know who's who right off from that. Presumably each ...

If you need a file name to tell you who collected data on your project ..... that, it seems to me, is a problem.

It’s a pretty big ask but maybe you could get the pre-rotated coordinates, etc. and use that to put the thing on a proper basis.

To me, this sounds like just another day at the office. At one employer the guys would set up the GPS base over a point and do an autonomous positio...

Date? Yes, certainly. Although that is usually imbedded within the dataset. If not it will be an attribute of the file itself. As Moe pointed out earl...

An investment, to be sure. And maybe for certain kinds of business model it won't pay off quickly. But I think that, in time, it is going to be seen a...

You could be using an alpha that isn't personalized. Or a half dozen other approaches. In my case, the check shots are given descriptors that identi...

So am I. At least I always have been. But I just can't ignore proven results.

There are a number of postings in this old thread stating that adjusting data is about spreading errors into places it doesn't belong. Wrong. So wrong...

I'm thinking maybe your statement didn't come out exactly as you intended. StarNet (or any LS adjustment software) does a fine job on any adjustment. ...

It wasn't all that bad a place. I've done time in far worse. Nevertheless, as I described, guys would take a number of check shots and do what they ha...

Because the foresight length is only 10 feet. With a target centering error of 0.003', plus other contributors, it makes sense. BTW - I usually (a...
