The Principles and Practice of Surveying
The only equipment needed for this Work in addition to the ordinary engineer's
transit is a set of stadia hairs in the telescope, and some form of graduated rod on
which distances may be read from the instrument. The two stadia hairs are ...

Surveying Instruments and their Operational Principles
5.2.1.1 Simple Distance Meters with Fixed Stadia Hairs The main constructional
element of simple distance meters with fixed stadia hairs is a geodetic telescope.
In the plane of the telescope graticule there are, as well as the cross-hairs, two ...

Kahmen/faig:surveying Geb
The oldest type of optical distance meter utilizes the basic stadia principle with
two or more horizontal stadia hairs on the reticule of the measuring telescope
and a graduated vertical rod at the target station. Early instruments were built by
Mon- ...

Surveyor Reference Manual
Stadia sighting depends on two horizontal crosshairs, known as stadia hairs,
within the telescope. These hairs are parallel to the horizontal crosshair and are
equally spaced above and below it. The stadia hairs are shortened so that they
will ...

Fundamentals of Surveying
In the tangential systems, the stadia hairs are not essential. However, two
readings are to be taken at the two targets at a fixed distance 'S' apart in the staff.
This is shown in Fig. 15.4. This requires two settings of the instrument at 61 and
62 and ...
Stadia system, again, may be (a) Fixed stadia system and (b) Movable stadia
system. (a) Fixed Stadia System: In this system the distance between the stadia
hairs is kept fixed and the intercepts across the fixed stadia hairs vary for staff
held at ...
11.3.2 The tach co meter As already noted, this is a transit theodolite that has
been specially adapted and fitted with stadia hairs on its diaphragm. The
magnification of the telescope is at least 20 to 30 diameters, with an aperture of at
least 40 ...

Surveying instruments equipped for stadia measurement have two additional
horizontal cross-hairs, called stadia hairs. They are placed equidistant above and
below the horizontal leveling cross-hair, Figure 12.11. The distance between the

Audel Carpenter's and Builder's Math, Plans, and Specifications
The stadia hairs may be adjustable, or they may be fixed permanently on the
diaphragm. When using the stadia, distances are measured by observing
through the telescope of a transit the space (on a graduated rod) included
between two ...

Stadia rod /\ Stadia hairs \ FIGURE 3.14. Measurement ofdistance using a stadia
rod. In this example,the stadia hairs in a sighting scope are separated by angle a
= 0.01 radians, and a 5-m stadia rod is placed a distance daway. We observe ...
