1.22.5. Triangulation survey work

Try these first

1. 1.

   What are the two major steps in triangulation survey work?

   Hint

   Think of the overall activities involved in a survey.

2. 2.

   What is the function of a baseline in triangulation?

   Hint

   Consider its role in forming the triangles.

3. 3.

   What is the first step in triangulation survey work?

   • Measuring angles
   • Reconnaissance survey
   • Erection of signals

   Hint

   Think about the planning phase of a survey.

4. 4.

   True or False: Computational work includes verifying observed angles.

   • True
   • False

   Hint

   Remember the importance of checks in surveying.

5. 5.

   A surveyor is tasked with triangulating a terrain. Describe in detail each step they would take during fieldwork and explain its significance.

   Hint

   Think of why each step is crucial to gather accurate survey data.

6. 6.

   In a triangulation survey, if the computed position of a point differs from its actual position, what could have gone wrong in the computational checks?

   Hint

   Connect errors to the processes that were supposed to ensure accuracy.
