Question 1.
What is EDM?
Show hintHide hint
Think about the function of distance measurement.
Question 2.
What is a reflecting prism?
Show hintHide hint
Consider its role in distance measurement.
3Question 3.
What does EDM stand for?
- Electronic Distance Measurement
- Environmental Distance Measurement
- Energy Distance Measurement
Show hintHide hint
Identify the full form of the acronym.
4Question 4.
True or False: The EDM can measure distances with an accuracy of 1 in 1000 to 1 in 10000.
- True
- False
Show hintHide hint
Think about the maximum accuracy discussed in the section.
Question 5.
You have an EDM that measures a distance of 1000 meters with a known error rate due to temperature. If the temperature drops, increasing the measurement error to ±10 mm/km, what will be your new estimated distance?
Show hintHide hint
Consider how the error scales with distance.
Question 6.
What factors would you consider when setting up an EDM in a forested area where prisms are used extensively? Discuss strategies to mitigate potential errors.
Show hintHide hint
Think about visibility and environmental impacts.
