Sketches of non-passive stations

Postby stripybadger » Fri Aug 03, 2018 1:14 pm

Passive stations (e.g. http://trigpointing.uk/trig/765) quite often have sketches of their location, which are obviously very helpful.

Is there any information at all on those that aren't passive stations? E.g. looking at http://trigpointing.uk/trig/21551 (a water tower) there's no information to suggest whether the rivet was at ground level, on the roof, on a gatepost... A sketch would be awesome, but is there even any information, anywhere, about these non-passive stations?

Short answer: Yes, sketches and other information about non-passives does exist but its not readily available on-line.
The OS documents are held at the National Archives in Kew and, so far, very little has been digitised. So its a case of
either visiting Kew or paying for selected documents to be scanned on your behalf.

This is something we've discussed before; the following link provides more details:

Thanks Ted, very interesting link.

Shame they haven't been digitised more proactively, I would say they're a key part of our heritage - but as a trig bagger I suppose I'm biased!

As a rule of thumb since trig points rely on line of sight to other trig points generally they are located up high. In the case of trig point on a water tower the TP would usually be at the top. I am sure though there are exceptions to this rule.
