3.2.5. Errors in EDM measurements

Try these first

1. 1.

   What are personal errors in EDM measurements?

   Hint

   Think about how a surveyor sets up and measures.

2. 2.

   List one example of instrumental errors.

   Hint

   Consider what can go wrong with the EDM itself.

3. 3.

   Which of the following is a type of instrumental error in EDM measurements?

   • Personal mistakes
   • Calibration errors
   • Environmental influences

   Hint

   Focus on errors that relate directly to the EDM.

4. 4.

   True or False: Personal errors cannot be minimized.

   • True
   • False

   Hint

   Think about how practices can improve accuracy.

5. 5.

   You are surveying in conditions where the atmospheric pressure is fluctuating rapidly. List the steps you would take to mitigate the effect of atmospheric errors during your EDM measurements.

   Hint

   Think about your preparation and adjustments needed.

6. 6.

   During a survey, you observe that cyclic errors seem to fluctuate with distance. How could you address this issue in practice?

   Hint

   Consider how frequencies affect your measurements.
