What do the acronyms OBT and OCIP mean on a survey plan?
Geographic Information Systems Asked by EBlake on July 28, 2021
When looking at survey plans for British Columbia, Canada, there are various acronyms used to describe survey markers. Ones that I do know include:
- BT – bearing tree
- CIP – capped iron post
- PP – "old-style" pipe post
- OIP – original iron post
I am, however, unsure of the acronyms OBT and OCIP. Could they mean "original bearing tree" and "original capped iron post"? If so, what would the qualifier "original" refer to? A previous/different survey plan?
I cannot seem to find answers elsewhere on the ‘net.
Per request in a comment, I added an image of the OCIP marking
One Answer
OBT “original bearing trees” (trees are blazed for future reference)
OCIP
CIP can be denoted as many items but traditionally this was Capped Iron Posts
[Disclaimer have used traditional surveying equipment, today it is more Laser and GPS guided]
