What is stadia rod ?

An ordinary levelling staff can be used if the sights are short but in tacheometry since the sights are usually of much greater length, therefore, an ordinary levelling staff cannot serve the purpose. But a specially designed graduated rod known as stadia rod is used.

How to Calculate Intercept on rod between two sighting wires?

Intercept on rod between two sighting wires calculator uses Intercept on rod=Stadia distance/((Focal length of telescope/Rod intercept)+Stadia constant) to calculate the Intercept on rod, The Intercept on rod between two sighting wires is the reading which we get from tacheometer on the stadia rod. Intercept on rod and is denoted by R symbol.

How to calculate Intercept on rod between two sighting wires using this online calculator? To use this online calculator for Intercept on rod between two sighting wires, enter Stadia distance (D), Focal length of telescope (f), Rod intercept (i) and Stadia constant (C) and hit the calculate button.

FAQ

What is Intercept on rod between two sighting wires?
The Intercept on rod between two sighting wires is the reading which we get from tacheometer on the stadia rod and is represented as R=D/((f/i)+C) or Intercept on rod=Stadia distance/((Focal length of telescope/Rod intercept)+Stadia constant). Stadia distance from instrument spindle to rod. , Focal length of telescope is measured as the distance from the main optic to the point where the image is formed, Rod intercept gives the reading from the rod and Stadia constant is integer ratio between the difference of the rod readings and the distance from the telescope to the rod.
How to calculate Intercept on rod between two sighting wires?
The Intercept on rod between two sighting wires is the reading which we get from tacheometer on the stadia rod is calculated using Intercept on rod=Stadia distance/((Focal length of telescope/Rod intercept)+Stadia constant). To calculate Intercept on rod between two sighting wires, you need Stadia distance (D), Focal length of telescope (f), Rod intercept (i) and Stadia constant (C). With our tool, you need to enter the respective value for Stadia distance, Focal length of telescope, Rod intercept and Stadia constant and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
