1.19.2. Methods of tacheometry

Try these first

1. 1.

   What is the purpose of the tacheometer in surveying?

   Hint

   Think about the functionalities it provides in surveying.

2. 2.

   Define staff intercept.

   Hint

   Consider what a levelling staff measures.

3. 3.

   What is the function of a tacheometer?

   • Distance measurement
   • Angle measurement
   • Both

   Hint

   Think about the different measurements required in surveying.

4. 4.

   True or False: The additive constant in tacheometry is typically set to 100.

   • True
   • False

   Hint

   Recall the common practices in tacheometry.

5. 5.

   A tacheometer records a staff intercept of 0.75m with an angle of elevation at 10 degrees. Calculate the horizontal distance.

   Hint

   Make sure to convert the angle to radians if necessary for your calculator.

6. 6.

   If the K value was mistakenly set to 150 instead of 100, and the staff intercept is 0.6m, what would be the new calculated distance?

   Hint

   Check how the K value affects your overall calculation.
