Shooting buddy of mine was a surveyor for years, civilian, not government.
He has a pretty low opinion of state "survey crews". Rightly, or wrongly, I don't know... he has gone on a rant about 'em before "bastards take 5 guys three days to survey something that I've done in 6 hours...".
From what little I know, modern civilian surveying GPS is accurate to a few centimeters - the intentional encrypted "blurring" of the signal was removed some years ago. It can be selectively turned back on at any moment, either globally, or regionally.
It still takes a GOOD GPS to get that kind of accuracy, however.
That's my understanding, anyway.
This is all second hand, so if there's a surveyor in the house, I bow to their experience.
