Duplicate listing

Recommended Posts

I suspect that HW3332 link

and HW3334 link

 

are the same listing and that both refer to the triangulation station under the US C. &G.S manhole cover.

 

Looks like folks are logging the actual observatory for HW332 but the data sheet is the same for both (I logged HW334 as the data sheet for that one also described the RMs)

 

Before I make a note on HW332 I wondered what others thought?

HW3332 (note third three) is the LEANDER MC CORMICK OBS building itself. Known as an 'Intersection' they are no longer used or recovered to NGS as covered by several threads on this forum. Still in play here though.

Sorry about the missing 3, that has been corrected. Normally the datasheet for an intersection station lists the point intersected. Here is the listing for HW3332 from NGS Data Explorer:

 

"HW3332'DESCRIBED BY COAST AND GEODETIC SURVEY 1965

HW3332'STATION UNIVERSITY IS LOCATED ON THE UNIVERSITY OF VIRGINIA PROPERTY

HW3332'IN THE SOUTH EDGE OF CHARLOTTESVILLE AT THE SITE OF THE LEANDER

Here is the datasheet for HW3334:

The location of both stations has the same description as you can see with additional information regarding the triangulation station and its reference marks. With some more digging I noticed that the datasheet locations are different:

 

HW3334: NAD 83(1993) POSITION- 38 01 58.01420(N) 078 31 21.17948(W) ADJUSTED

HW3332: NAD 83(1993) POSITION- 38 01 58.18429(N) 078 31 20.52514(W) ADJUSTED

 

So now I think that they are two separate stations but that the description for the intersection station got mixed up with the triangulation station nearby?

I have been the navigator for our jaunts until we get to the site, I have been the decipher of the NGS datasheets as well as the GC datasheets. I have our laptop on my lap as we go with both the Delorme Topo Map program running while attached to the little gps unit and also our GSAK database up and handy. So I have gotten very familiar with how to look at these to let my hubby have the best on the spot info....

 

On the GC page it list this at the top.

These 2 lines will tell you all about the "Style" and "Type" of the mark.

 

Then the next line --

 

 

Setting: setting not listed - see description

 

Is the way the mark is set. When you see this "setting not listed and see description" - It can mean an unusual way of the mark being set or an intersection station as this mark is.

 

The important original "Documented History" is where the major clue for where the confusion is...

 

 

Documented History (by the NGS)

 

01/01/1965 by CGS (FIRST OBSERVED)

 

DESCRIBED BY COAST AND GEODETIC SURVEY 1965 STATION UNIVERSITY IS LOCATED ON THE UNIVERSITY OF VIRGINIA PROPERTY IN THE SOUTH EDGE OF CHARLOTTESVILLE AT THE SITE OF THE LEANDER MC CORMICK OBSERVATORY. STATION UNIVERSITY IS 37 FEET WEST OF THE WEST EDGE OF THE OBSERVATORY, 33 FEET NORTH OF THE CENTER OF THE ROAD, 26 FEET EAST OR THE SOUTHEAST CORNER OF A BRICK BUILDING AND 25 FEET EAST OF THE NORTHEAST CORNER OF THE SAME BUILDING. NOTE--THE DIRECTION WAS TAKEN TO THE CENTER OF THE POLAR AND DECLINATION AXIS OF THE TELESCOPE.

 

Here you see the info of the 1965 Station marked University as a reference that was used for the intersection taken to the exact center of the Polar and Declination Axis of the Telescope. The information of Station University was included just for clarification, or the Reference for the Intersection Station.

 

So, two different data sheets for two different Designations and Types of marks - one a Benchmark Disk and the other - the Intersection Station.

 

That is a beautiful old Observatory!
