Those strange yellow viewing devices

#1
What are those yellow viewing devices, on tripods, that civil engineers/architects use on the street from time to time. And what is the function of these devices? I know, it's a bone question. :oops:

They called Theodolites. Functionwise, haven't got a clue !!!!!

Cheers, saintstone.

According to that great bastion of impartiality and objectivity, Wiki:

"A theodolite is an instrument for measuring both horizontal and vertical angles, as used in triangulation networks. It is a key tool in surveying and engineering work, but theodolites have been adapted for other specialized purposes in fields like meteorology and rocket launch technology. A modern theodolite consists of a telescope mounted movably within two perpendicular axes, the horizontal or trunnion axis, and the vertical axis. When the telescope is pointed at a desired object, the angle of each of these axes can be measured with great precision, typically on the scale of arcseconds."

You learn something new everyday.

You would probably get more info on these in the Gunners forum.

Theodolites, or directors as they were also know were used extensively before GPS came into general use. Each Battery had a Survey Sgt who would use a director for laying on the Guns. There was also a dedicated Survey Troop based at RSA Larkhill, although I believe that nowadays they are laid up and largely defunct, with the associated knowledge of their use rapidly dissappearing.

THEODOLITE, not THALIDOMIDE, but what do you expect from a wedgehead, but very funny though.

(My bold). Where have I heard that before?

I meant more as in further info, not better Knocker!

It used to be a proper trade with us as well but is now saddly disappearing.

All hail GPS, and let's hope that the satellites are never switched off!

I think you'll find every field regiment in the artillery had a dedicated survey troop. That was the case up to the late 1980s, but I'm not too sure of the state of play today.

Glad you asked. I see them everywehere but never wanted to ask the question myself.

Could be one of three devices.

a) A theodolite: as described earlier used to set out marks for new buildings (corner points ect) or to establish location of existing equipment(manholes etc)

b) A level: one operative behind telescope, another holding a measuring staff (giant ruler), used to establish the height (or depth)of things.

c) A total station: cross between a theodolite and a GPS, one operative behind the telescope and one holding a pole with an optical target on the top. Place the target on the item to be measured, sight onto it press record and its coordinates and height are recorded.

Total stations have now largly replaced the true theodolite, easier to use and more information.
