Challenge Problems
Push your limits with advanced challenges
A survey requires creating a detailed topographic map of a hilly region. If the initial plan only allows for 40% longitudinal overlap, discuss the potential impacts and propose adjustments.
💡 Hint: Think about the importance of full coverage.
Calculate the number of required photographs for a flight line length of 2000 meters and a necessary airbase of 100 meters with the desired overlap percentage.
💡 Hint: Consider how far each photo needs to cover.
