Question 1

What is the primary function of a tacheometer?

  • To measure only angles
  • To determine distances and angles
  • To calculate areas

💡 Hint: Think about what surveyors need when mapping areas.

Question 2

True or False: The constant C in tacheometric calculations compensates for the height of the instrument above the ground.

  • True
  • False

💡 Hint: Consider how instrument height affects measurements.

Challenge Problems

Push your limits with challenges.

Question 1

Given a tacheometer with K=100 and C=0, a distance reading with slopes is needed at point A with stadia readings of 3.000m and 2.000m when the angle of elevation is 30 degrees. Calculate horizontal distance and RL if the benchmark is 900m.

💡 Hint: Follow steps: Find height difference from readings and apply the formulas to find horizontal distance!

Question 2

From two tacheometric observations with different staff readings and angles, derive the overall vertical height drop if the last known RL was 750m. The last observation readings indicate angles of depression and the staff readings being 0.800m and 2.400m.

💡 Hint: Remember to consider both angles in your calculations to arrive at the right total distance.
