1.18. Theodolite Surveys

Try these first

1. 1.

   Describe what a theodolite is used for.

   Hint

   Think about its applications in mapping and construction.

2. 2.

   What is the main advantage of using an electronic theodolite?

   Hint

   Consider how it affects the ease of measurements.

3. 3.

   What is the primary function of a theodolite?

   • To measure angles
   • To measure distances
   • To draw maps

   Hint

   Consider the main job of the instrument.

4. 4.

   True or False: The repetition method is preferred for measuring multiple angles.

   • True
   • False

   Hint

   Think about the definitions of both methods.

5. 5.

   During a survey, a surveyor measures horizontal angles of 45°, 90°, and 135° using the reiteration method. If the readings had closing errors of 2° total, what adjustment should be applied to each angle?

   Hint

   Distributing the closure error evenly helps maintain relation among angles.

6. 6.

   You are conducting a survey for a park layout using theodolite traversing. What steps will you take to ensure high accuracy in your angle measurements?

   Hint

   Think about techniques to avoid common errors.
