Imperial entanglements are more the rule than the exception in much of the Mountain West. This is especially true of Sections that include Mineral Surveys, and the subsequent "lotting" of the remaining USA lands within the Section, which may or may not have been conveyed (patented) under various authorities based on said supplemental plats. It is actually somewhat rare for the subdivisional lines these parcels to have been "surveyed" let alone fenced. East-West Center Lines of such Sections need to be established "properly" regardless of who owns the lands (Public Domain or Private). Yeah... it's ONLY a tenth or two depending on your latitude (more in Alaska), but it's not that difficult to do it "by the book."?ÿ ?ÿ?ÿ
about 50% of private land have fed mineral estate in my state. It's difficult to stake a sectional corner without Fed interest involved.?ÿ

But you don??t dimple monuments LOL J/K
In my area the midpoint of 1 mile is south about 0.13 feet of a straight line, still on the 3-1/4? monument cap.

Speak for yourself Dave, a "datum point" dimple is SOP around these parts. Of course a BIG Cap helps keep the "point" on the cap!

Here is the proportion by geodetic positions spreadsheet I mentioned earlier in this thread.?ÿ ?ÿIt is set up for double proportion but if you want to do a single proportion just use one line.?ÿ ?ÿ Although it is set up for a cardinal line PLSS rectangular?ÿ in the graphic layout, I am pretty sure it will work on any bearings when doing a one line single or a double proportion.?ÿ But I'm retired and can't remember as well as I would like to or used to, please check it and verify using non cardinal proportions.?ÿ ?ÿMaybe somebody who has data can do so and report back on this thread.?ÿ Pretty sure it will do that.?ÿ ?ÿRecord distances can be any unit as long as is same units throughout entry.?ÿ ?ÿThe datum is not really used, I know it works both on NAD 27 and NAD 83.?ÿ?ÿ
@loyal mighty moe has stated on numerous occasions that he doesn??t dimple caps (unless I have him confused with someone else). I guess the joke is no longer funny if it has to be explained.
I put a dimple in the center.
Interesting discussion, I'm glad I brought this up and to clarify for some including my dear friend Mr.Cow my intention was to find a mathematical aid, another tool only, that would act as a check to my cad program. This by no means was to replace or substitute for anything normally required in a surveyors breakdown of a section, no abandonment from the BLM manual, regular exhausting search for monuments on the ground and common sense. I've been working on it since the posting of this question with a programmer who wrote some script, yesterday I got something to check with manual and cad calculations so it works. I'd be happy to share this with anyone interested.
I'd also be interested in the program you have when you get back in Northern Surveyor, man I remember the cold in Maine, -45 degrees, everybody dressed like you were in George Washington's army. Sitting by the wood stove....
Thanks to all who added to this post, I always learn something here!
I'm just a surveyor continually trying to find north Mr. Cow,
See You, Happy New Year!
If anyone is needing CAPD contact me. I have all the limited documentation that exists as well. Even have it all ready to load in a cuix file so installing it is copy and paste to a defined directory and then load the cuix into your version of AutoCad.
I have all the legacy CAPD files plus a lot more custom CAPD lisp routines that I helped build (in a very limited way) at the NV BLM. Besides myself and a BLM friend in Idaho and one other guy at the FS, nobody else I know of has added to CAPD since Tommy Noble had to stop working on it sometime in the late 90??s or the early 2000??s.
I would also be interested in teaching CAPD to anyone interested. Contact me and we can discuss the services I would consider offering.

@northernsurveyor Back in early 2000s I used a program called BOGO, the creation of a BLM surveyor for doing mostly geodetic computations and township protractions. It was a wonderful tool for this application. I suppose if you are familiar with it you likely know a lot more about it and likely the individual that wrote it. I still have a couple of versions but very few sections and townships to protract these days.?ÿ
i remember hearing about BOGO but I??ve never used it or seen anyone running it. Was that an Alaska BLM toy? I did try very unsuccessfully years ago to revive Alaska??s Reds JuJu stuff that consisted of lots of spreadsheets and lisp routines. It somehow worked with or in hand with CAPD. It had a bunch of scripts too that were no longer functional by the time I got my hands on as the Windows environment had moved on.
You made me go back in the way back in time machine. If I now remember correctly wasn??t BOGO a part of Red??s JuJu? I never knew Red but I heard that he was a genius of sorts. I think his real name was Tom and thus the T&T projection in CAPD. Named after Tom Noble and Red. But I don??t remember Red??s last name as I never met him and rarely do names stick in my head unless I meet someone face to face (a product of a misspent youth I believe).
@kanehell Not Red, Blair I believe, it is a custom AK BLM program written by one of their surveyors , no windows, ran it off read files or command line to store values, cogo using lat/long and chains or feet, intersections, output to State Plane or geodetic. Protraction would create every aliquot part position down to 5 acres if you chose. I thought it was pretty bada$$ but don??t believe it was available commercially.?ÿ
I have a vague memory of hearing about it. My old boss in Nevada, Mike Harmening, used to talk about it.
I started out with CMM running the good old CStuf command (about the only command I remember now). Then I figured out that the draftsman was using CAPD and I started playing with it. I never figured out how to draft with it really. But I quickly figured out it??s computational power! When I finally figured out how to kick points into TGO and of course later TBC, I never looked back at CMM.?ÿ
We are thinking of two totally different guys. The person I mentioned who??s nickname was Red was actually named Tom Wholwend. He was behind Red??s JuJu which may or may not have derived out of BOGO. But I believe he also helped Tommy Noble with some aspects of CAPD or maybe his Red??s JuJu was sort of in competition with CAPD. I heard the history years ago and it??s fuzzy now but I am almost certain that I got the names above correct.
Reds JuJu wasn??t BOGO. It was all script based but I never taught myself scripting. I sort of started to in a failed attempt to see what it had to offer but I think I was ordered to do some actual work.
