@gary_g The surface rights portion of this case is a pretty straightforward example of AP. The mineral rights treatment is an interesting twist tha...

@surveygrug Under the "Adjustment Statistical Summary" you will now have an "error factor" for coordinates as well as angles, distances, zenith ang...

Show me the case law. There has to be some.

I got one for under $7k total, including the mated rod and batteries. A second one ran under $10k. You have to wait for the deals. As a government age...

In such a case it seems probable that the fence was built in reliance on the pin. That would be evidence that at least one of the adjoiners knew about...

yes. Usually 2 sets for control and one set for boundary ties. Although I posted the other day about how great single shots with an AP20 tilt sensor w...

@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...
