This is one I haven??t seen before. We staked to an as-built point that we shot two or three years ago and couldn??t figure out why the coordinate on the planset was wrong. It appears that one digit is different between our issued map and their sheet that included a scanned image of our map. So, we dug until we found the wet signed file copy. On the two images I??m uploading, point 3710 is the issue. One image from our file copy and the other from the construction plans. I cut out the first few digits for discretion. Anyone have a clue what happened?

I wonder if the construction plans somehow relied on OCR of the numbers on your original map to create their plan sheet??? Seems like a stretch, though.
Looks like an OCR error. (scan to text)
FrozenNorth got there 1st
Looks like an OCR issue, but it is VERY strange that would be the only "6" read as an "8"... Weird.
The Design Engineer (or Draftsman):
1. Didn't know how to import dbf, excel, comma delimited, or clipped images
And
2. Transcribed your values wrong.
OCR would be rare for this to be the only 'mistake'.

Could be the only mistake not caught.
We're going to try to find out for sure what happened. We do know that what was sent out had the right number since the contractor saved his copy from the previous phase and it matches our file copy. Somewhere between phase 1 and 2 plans (we issued once prior to phase 1) something happened.

I remember Reading aan article Some years ago ... it pointed to a glitch in the scanning/copy software ... was a bad thing for bankers

Sounds like a bad thing for surveyors too!
