PL added to name

[+kpejr]

I found EZ6531 it was originally stamped 1983 and named annex. It was restamped 2008 and is now named pl Annex or plannex.

 

Does anyone know why they did this or what it means. I downloaded the new datasheet from the NGS site and it didn't have any information. I aslo search their site for pl annex and plannex.

 

EZ6531

 

Thanks

If I were to guess - and I am, since I am by far the most knowledgeable person here - I'd say that that station was used in a 2008 project,and "PL" is the project name, a party member's initials or some other code used in relation to the project.

 

Now.. everyone.. how off am I?

I think projects aren't supposed to restamp disks unless there is a documented change, like a reset. But we've seen an example or two of that happening. A couple years ago this post showed a disk that had about 5 dates on it and NGS had added a note to the RB1488 data sheet asking whoever was doing it to stop.

That's a strange one! The last documented recovery was when one of our members (Kyle) stopped by in 2007. I'm not aware of any area surveyor or NCGS personnel with the initials "PL", but I'll ask around to see if anyone knows what this means.

Looks to me as if someone is cruising for a $250 fine.

AZcachemeister correctly surmised:

LOL. As it turns out, the crime was not the stamping. It was moving the mark and not telling anybody.

 

Here's the explanation from Gary Thompson, Director of the North Carolina Geodetic Survey.

We changed the stamping on "Annex" We discovered that a contractor

removed the disk and set it in a new sidewalk. The mark has been moved

from its original location. When I visited the site after someone

reported that the coordinates were off, I knew what had happened. We

stamped a new name and determined the coordinates. We're submitting a

destroyed report to NGS for "Annex" and a new description for "Plannex".

I wonder how far off it was. Quite likely less than the accuracy of eyeball estimation of the tie distances?

Hi, Bill,

 

It will be interesting to compare the coordinates, when they become available. Meanwhile, you were correct when you said, "I think projects aren't supposed to restamp disks unless there is a documented change, like a reset." That describes the situation, exactly.

Thanks for everyones help. I thought it was changed to plannex, The PL was too lined up with the ANEX to be anything else. I was just eyeballing it, so I have no idea how far the coordinates were off.

So why did they add the letters "PL," do you know, Paul?

Hi, Patty,

 

It beats me! I'm still trying to figure out why the station was named ANNEX. The only things at the intersection are a motor pool lot, a gas station, and a donut shop.

 

Perhaps PL equals "Property Line". In 2008, the right-of-way for the adjacent street was moved 3 feet, as shown in the plat, below.

Now fixed. Although the new station's coordinates have not been published, the data sheet for ANNEX was updated yesterday. If you look at EZ6592 (at the other end of the sidewalk), you will see the same notation.

It still doesn't make total sense. It really appears like the same disk in the same setting both before and after the marking. I suppose they could have reset it, repositioned it and then waited 6-10 months before going out and restamping it.

 

A pretty odd one.

I agree with Jerry Wahl - from the photos in the geocaching data base; the 2006 photos clearly show the same setting as the 2008 photos. This mark would have had to have been moved before 2006 and after 1983. The movement must have been discovered in 2008 and corrected by the NCGS personnel in 2008.

Isn't that what Gary said from the NCGS?

removed the disk and set it in a new sidewalk. The mark has been moved

from its original location. When I visited the site after someone

I read that as they FOUND it moved in 2008 - meaning someone moved it before then - and in 2008 they stamped it and filed the paperwork. Obviously since there are photos from 2006 here, I'd say it happened before then, too.

The only reason I can think of for adding PL to the stamping is that someone must have reset the mark with the original disk (or post) and thought everything was AOK. When it was discovered the added PL to it so it would be confused with the older mark.

 

I discovered a BM once that had been reset by those who disturbed it. The contractors thought the would not be found out but I just happened to drive by the area (4-way stop intersection) one weekend and saw the post laying on its side. A few month later when I was working nearby I went over to get the disk and found the post set back into the ground. Had I not seen the marker laying on its side that one Sunday maybe no one would ever have known about it. Its was just luck that I took this way home one day.
