Was looking at a plat today with bearings all reading something like N 43d 32'41.53" E.
The longest dimension on the entire plat is approximately one-half mile.
At a distance of 50 miles one one-hundredth of an arc-second amounts to 0.013 feet.
Well said and point made.
But if you are talking about distance on surface of the earth instead of a bearing, 0.01 arc seconds is about 1 foot. True for both latitude and longitude at the equator and true for latitude all the way to the poles.
It's likely someone had the labeling set wrong when they plotted the final. It pays to look at what you are signing...
I agree
that we should absolutely read what we sign, but what happened to "map check". Whether the computer labels the line or not it SHOULD be checked for closure and area. I had a set of highway plans with the bearings to the ten thousandth, just plain dumb to my way of thinking.

I agree
In terms of an angle of measure 1" of arc inscribes about 1' in 40 miles.
