Hi Greg,
The cadastre is a provincial entity:
https://www2.gov.bc.ca/gov/content/data/geographic-data-services/land-use/integrated-cadastral-fabric
A quick search didn't reveal accuracy specs but because these are legal
entities they have to be tight. Just talked to someone who manged this
for our municipality. He says 10 cm, 30 at the worst and the orthophoot
tie in to the cadastre also very good, at least at ground level.
"Or does your jurisdiction have a requirement for coordinates good to
<10cm to be submitted on transfer, and there really is a survey tied to
CSRS?"
This does seem to be the case here. How is it done in Massachusetts?
I've checked several other points, see previous posts.
Thanks Greg . . . . .

Cheers, Spring

I don't konw why you believe the cadastre to be sub-meter:
What is the published accuracy spec?
How many other points have you checked?
Perhaps you can answer those on-thread.

<10cm to be submitted on transfer, and there really is a survey tied to
CSRS? This would very surprising to me, but Massachusetts doesn't work
that way at all.
