3.3.10.4. Tilting Axis or Tilt Error

Try these first

1. 1.

   What is tilt error?

   Hint

   Think about how alignment affects measurements.

2. 2.

   Why is calibration important?

   Hint

   Consider what happens if instruments aren't accurate.

3. 3.

   What effect does tilt error have on the Total Station measurements?

   • No effect on measurements
   • Inaccuracy in horizontal readings
   • Inaccuracy in vertical readings

   Hint

   Think about what happens when the alignment isn't right.

4. 4.

   True or False: Tilt error can be corrected by measuring on both faces of the instrument.

   • True
   • False

   Hint

   Consider if averaging data would help.

5. 5.

   A construction survey on a hillside led to tilt error being discovered after the measurements were taken. Describe the impact this might have on future construction stages.

   Hint

   Consider how precision is critical in construction.

6. 6.

   Calculate the angular discrepancy introduced by a tilt error that measures 2 degrees off when set to an angle of 45 degrees. How would this affect horizontal measurements?

   Hint

   Think about the geometric relationships in surveying.
