Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does a scale of 1:5000 indicate?
- 1 inch on photo equals 5000 inches in reality
- 1 cm on photo equals 5000 cm in reality
- 1 meter on photo equals 5000 meters in reality
💡 Hint: Consider how the ratios translate in real fractions.
Question 2
True or False: Relief displacement is the same for all terrain heights.
- True
- False
💡 Hint: Think about how height affects visual representation in photos.

Challenge Problems
Push your limits with challenges.
Question 1
A camera at a 2000 m altitude captures a 60 m high building. If the image of the building displays a relief displacement of 30 mm, determine the flying height using the displacement formula.
💡 Hint: Start solving through the formula.
Question 2
In a photography survey, the flying height can be shifted. If at 1800 m we have three terrain heights measured as 200 m, 500 m, and 350 m, determine the maximum visible scale using the plane's performance ratio.
💡 Hint: Remember how focusing on the tallest structure can affect the scale calculations.
