Challenge Problems
Push your limits with advanced challenges
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?
💡 Hint: Consider how the error scales with distance.
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.
💡 Hint: Think about visibility and environmental impacts.
