Challenge Problems
Push your limits with advanced challenges
Given a line on a photograph that measures 15 cm and the corresponding ground distance is 300 m. What is the scale? If the terrain elevation is known to be 200 m with a focal length of 35 mm, calculate the flying height.
💡 Hint: Convert units and check calculations based on the height differences.
If an aerial photograph shows a distance of 5 cm corresponding to 100 m on the ground, find the height of the aircraft if the terrain elevation is 150 m and the focal length is 50 mm.
💡 Hint: Ensure you use the correct scale and rearrange the formula accurately.
