1.19. Tacheometry

Try these first

1. 1.

   What is a tacheometer?

   Hint

   Think of instruments used in surveying.

2. 2.

   What are stadia hairs used for?

   Hint

   Consider how distance is measured with a leveling rod.

3. 3.

   What is the main purpose of tacheometry?

   • Measure angles
   • Determine distances
   • Calculate elevations

   Hint

   Think about what tacheometry is used for in surveying.

4. 4.

   True or False: A tacheometer can only be used in flat terrains.

   • True
   • False

   Hint

   Consider the versatility of the tacheometer.

5. 5.

   Calculate the horizontal distance between a tacheometer and level staff with a staff intercept of 1.5 m. If K is 100 and C is 0, what is D?

   Hint

   Remember the formula for distance calculation.

6. 6.

   In a scenario where the staff is above the line of sight, the staff intercept is found to be 1.8 m, with a vertical angle of 15 degrees. Calculate the adjusted distance using trigonometry.

   Hint

   Apply the trigonometry principles regarding vertical angles and right triangles.
