I know some have abused these. But, any good tool can be abused. Because abuse is done by novices, in no manner discredits their actual use.
Kinda like women. Excellent device for many wonderful things. Don't let those who abuse them, block you from their proper use!!

In Arkansas, min stds (proposed) say we should publish ground scale. (Not unscaled grid distances)?ÿ I think this kind of legislation is a form of abuse, ie, legislation, to simplify, that in reality greatly adds to the complexity.
We should be able to publish pure SPC, with appropriate metadata.
Thanks,

Any accurately laid out control network can be used with a projected file. No calibration necessary.
I recently re-controlled one of mine from 1992, an extensive network covering many townships. I didn't do any calibrations and got within a few tenths across 20 plus miles of traverses.
All using a pre-projected file. Simply adjusted the scale factors to fit the known quad sheet elevations and went to the field and hit control better than I ever expected.?ÿ
And if the control you are using is GPS based then calibrations are not needed.?ÿ

You??re a nut.
Distances on a survey given to a client and/or recorded should be ground distances.
Bearing basis should be whatever makes sense for the project, and unambiguously related to geodetic north by a note if you have that info.
A coordinate table in pure SPC could be useful and is preferable to a confusing conversion to ground coordinates that look like SPC. Don't forget to identify the datum realization.

The definition of localization:
The mutilatiom of otherwise perfectly good survey data through the use of unnecessary mathematical violence.
The definition of localization:
If Ambrose Bierce had been a surveyor he would have said it exactly like that.
That's the nicest thing anyone has said to me in a long time.?ÿ Thank you????
For example, using some benchmarks that are all on the same line (like along a highway).
Or along an airport runway, which is generally straighter than your ordinary highway.?ÿ I stumbled into that one morning 24 years ago in Helena, Montana.?ÿ
Fortunately I was looking at my "tilt" parameters and saw right away what was wrong as soon as the third point came into the vertical mix.

Surveying on grid brgs and scale, is only surveying on geodetic at central meridian, and only accumulates enough error, as grid/ground generates!
I think you have it flipped..
Every model for every datum is imperfect. All porjections distort positions and remove them from reality. Modification of projected coordinates actually reduces the distortion.?ÿ
@nate-the-surveyor I meant that with a grin, too. ?ÿJust trying to be silly. ?ÿI apologize. ?ÿCarry on.
