When I was a survey manager the call for help I most often got was from CADD people working on an engineering project who imported our survey data and...

Agree that results are optimistic when seeking true height. The precision of 180 observations do not indicate a truly accurate (correct) height. We p...

I suppose the most memorable pin cushion we found were 3 monuments marking one corner all with the same surveyor's number atop. You can put a bushel b...

Maybe I shouldn't say we didn't get very far based on what I'm reading here. We did get ROW staking removed from the construction manual. In other wor...

@peter-lothian I hope before I die some private owner will have the resources to try one of these in court. The outcome would be interesting if argued...

@hbrisson I sent it by private message

I've had my eye on this topic for a few days. It's hard for an old fella like me to believe it was raised. We never ever trusted linework for calculat...

@not-my-real-name It was late and I basically read the subject line and responded. We don't have stone walls on or near right of way here. We do ha...

If you know what your boundary is you have your line. It's your boundary.

This reminds me of our new local city sub division ordinance a while back that required surveyors to " state plain coordinates on all new sub division...

If lot 6 was in coincidence with the govt line at the time it came into being, it still is. Pretty simple. The new survey should be retracing, not res...

Like assuming the correct location is 9 feet from an original looking monument?

I was trained not to set a control point where someone might be searching for a property corner. Did we quit that practice? Also was trained to figure...

ROW design is developed from road design alignment. Everything else is once or more removed from that criteria.

That's because the original design for state plane anticipated everyone would reduce ground measurements to sea level. There was no 1: 10000 criterion...

I'm not sure what the question is referencing. I'd need to hear the question and answer. I see the NGS zone design criteria has been relaxed to 50 ppm...

@mathteacher My opinion is that for 99% of surveying purposes any distortion less than 20 ppm between grid and ground is not worth discussing other th...

If this discussion doesn't scare you enough to use SPCS2022 as ground it should. We saw the scale settings mishandled by the users and the software e...

@field-dog 2 cm off on one point and 2 cm off the other way on the second RTK derived control point and walla. 0.06 - 0.07'
