You can’t fix stupid, it’s a conscious decision to do something you know isn’t right.
You seem to be implying that I was “stupid” and what I did was to consciously do something I knew was wrong and if that is what you are attempting to do I would submit that they fella who asked me to do this was told firmly and clearly the need to perform a proper survey and he was the one who insisted on staking a line between the two points he identified. I will not walk away from an opportunity to make easy money and any surveyor would be foolish to turn up his nose at easy money however I also recognized that I had to protect myself and that is where I used his very words in the contract and stating very clearly that the client did not want a proper survey and that he identified the points to place stakes between. It is not an uncommon thing to be asked but he balked after I put it in writing what he asked.
Miscommunication. I was referring to the potential client.
I would never imply or accuse a Surveyor of being stupid, period.
People/clients always have either an ignorant or deceptively concocted idea of how they wish things to unfold in their favor.
I definitely did not intend for you to feel I was talking about you at all. I applauded the contract being dismissed. Carry on. 🙂
I found this explanation and nice illustrations. It shows how you can sort of do the job of laying out a straight line on flat ground with 3 poles, but 4 helps get it more accurate, and 4 lets you go over a hill that hides the end points from each other.

It doesn’t address the case where there are 2 hills. That was what was on my mind in the post above, and I still don’t see how you could do that with 4 poles.
.Bill, I imagine every surveyor has done this many times, I know I have, I generally use several bipods and prism poles stacked on the end points and raised as high as they will go with lots of flagging. And the middle points are a couple of range poles.
As for your particular question. I believe it is working on some basic assumptions that the line and end points are all intervisible with no major geoidal undulations blocking the view.
4 guys can run a straight line between existing corners, three can, two can, although it gets more complicated as the number shrinks. It’s how the country was laid out, run a straight line from one corner to the next measuring the distance as you go, measure the misclosure at the second corner and shift points along the line over by a ratio of the misclosure. Easy ???? ????

Where can I get the robotic version of this?
Or. You can set up a TS or Transit, and look through the barrel of the scope for line as well.
Staff compass is really fast…have the rodman use flo pink painted lath. I have found my Disto really likes the flo pink lath too, the one I have can give horizontal distance.
The point of departure on this branch of the thread was the comment that the land owner could do it with range poles, no instruments. I was trying to figure out the assumptions and limitations of that method.

Secondly, the person who hires you has to have an interest in the land that you are asked to survey.
Interesting. Can you provide a cite for such a requirement?

I’m with Mike. It is not a requirement.
I will only survey for the owner or buyer.
It is an ethical solution for me, they are the only ones that are directly involved in the transaction and whose names will appear in the public records concerning the property.
The only exception to that rule is when a Title Company wants me to survey a property to solve a problem for the owner.

I too only work for the owner or buyer with a substantial retainer. The only exceptions are title companies but I avoid most ALTA Surveys simply because the people who seem to call me are damned morons that piss me off with their utter ignorance.
It’s difficult to think of surveys that aren’t at the owner’s or soon to be owner’s request. It often has nothing to do with selling or buying, and it may not be the owner of the surface, many mineral surveys are done every day and that is by the request of the mineral owner or lessee, I’m off to do one today. Even locating a POD miles from the owner’s property is at a person request who has at least a partial ownership in the POD. I suppose some large mapping projects will survey lands without the owner’s consent. Other than that or GIS work I can’t think of much.
