What is the length of stadia rod?
3-5 meters
A stadia rod is usually of one piece, having 3-5 meters length. A stadia rod graduated in 5 mm (i.e. 0.005 m) for smaller distances and while for longer distances, the rod may be graduated in 1 cm (i.e. 0.01 m).
What is stadia used to measure?
stadia- 1 A method of surveying in which distances and elevations are obtained by observing the interval on a graduated, upright rod (stadia rod) intercepted by two parallel horizontal lines (stadia hairs or stadia wires) in a surveyor’s transit set up at a distance from the rod.
What is the formula for stadia lines?
These lines are termed Stadia Lines or Stadia Hairs. When used with an Engineering Grade Rod, the distance from the instrument to the rod can be determined quickly by subtracting the bottom stadia reading from the top reading and multiplying the difference by 100.
What is stadia rod in surveying?
: a graduated rod used with an instrument having stadia hairs to measure the distance from the observation point to the place where the rod is positioned by observation of the length of rod subtended by the distance between the stadia hairs when these are fixed or of the space between the stadia hairs when they are …
What is stadia in surveying?
Definition of stadia : a surveying method for determination of distances and differences of elevation by means of a telescopic instrument having two horizontal lines through which the marks on a graduated rod are observed also : the instrument or rod.
What is the least count of stadia rod?
The stadia rod or staff used with tacheometry may be usual type of levelling staff having least count of 0.005m. Stadia rod is usually in one piece but for easy transport it may be folding.
What is the least count of stadia rod in M?
Stadia rod is of one piece having 3 to 5 meters length. The smallest subdivision is usually 5 mm.

What is the difference between level staff and stadia rod?
For small distances ( up to 100 meters) a level staff may be used for tacheometric surveying. But for greater distances stadia rod is needed. Stadia rod is of one piece having 3 to 5 meters length.
What is stadia line in optical instrument?
STADIA: Optical Distance Measuring. Optical instruments require a vertical and horizontal crosshair to be functional. Some optical instruments also have two short horizontal lines, one above and one below the horizontal crosshair. These lines are termed Stadia Lines or Stadia Hairs.
