Witness Post?

 

I am totally new at benchmarking. I would like to know if this is a witness post?

I can't bring up your link [from one computer network--this one works fine].

 

Generally there are two types of witness post that I have seen in common use for the marks in the data base. The older one is a steel post bearing white sign with black letters saying something like "Do not disturb nearby survey mark" and the newer one is an orange plastic post with the lettering on it. Other agencies may have customized similar ones.

I am not sure why you can't see the picture. It is an orange post with the words "survey marker" on it and NOAA.

Hi Fenderstrat:

Yes, that sure is witness post. See here for LOTS more: The new Dusty Jacket site

That an A-10 on that icon? Welcome to benchmark hunting!

AS far as witness posts go, I rather liked this one: AI8458. It's attached to a traffic sign. It should, hopefully, last for a long while. Most seem to disappear very quickly. The big question is why it took us twenty minutes to find it? Outside of the coordinates being a hundred-forty-eight feet off...

Fenderstrat -

 

What you have there is your basic "Orange Carsonite Witness Post", probably the second most common type (the first being the plain, old 1X2).

 

Carsonite International is the company that makes those orange posts (and the blue ones and yellow ones, etc etc, for other applications like buried TV cable, etc etc).

Thanks for all the info. Yes that is an A-10 avatar. I am active duty , nearly 24yrs, and the A-10 was the first a/c I worked. Although I am now at a F-16 base I have never lost my love of the A-10.

Hi Fenderstrat72. Found your forum while searching witness posts and benchmarks. I was only USAF for 4-years, but was stationed at MBAFB from 77-80 working PMEL. We transitioned from A7-D's to A-10's during that time. Checked Google Earth from way over here in California and see lots of changes at (what was) MBAFB. PMEL lab is gone. Waypoint-Willie
