Challenge Problems
Push your limits with advanced challenges
A photo is taken with a tilt angle of 12 degrees, flying height of 750m, and the focal length is 35mm. Calculate the scale of a point whose elevation is 150m if its y-coordinate relative to nadir is 200 units.
💡 Hint: Make sure to convert degrees to radians for calculations.
Discuss how varying flying heights affect measurements in tilted photographs, providing an example with numerical details.
💡 Hint: Contrast between low and high flights, think about image clarity.
