Question
Download Solution PDFWhen utilizing the stadia method of tacheometry for distance measurement, the stadia interval factor (k) plays a crucial role. Assuming the instrument constant (i) is zero, which of the following is true about the stadia interval factor in the context of horizontal distances?
Answer (Detailed Solution Below)

The stadia method of tachometry is used to measure horizontal distances using the formula:
\( D = kS + i \)
- \( D \) = Horizontal distance
- \( k \) = Stadia interval factor (typically around 100)
- \( S \) = Stadia interval (difference between upper and lower stadia readings)
- \( i \) = Instrument constant (assumed 0 in modern instruments)
Since \( i = 0 \) for properly calibrated instruments, the equation simplifies to:
\( D = kS \)
The horizontal distance (D) to the rod is directly proportional to the stadia interval (S) and can be calculated using the formula \( D = kS \).
