Question 1.
Define air-base in the context of aerial photography.
Show hintHide hint
Think about how photography needs spatial arrangements for clarity.
Question 2.
Why is overlap necessary in aerial photographs?
Show hintHide hint
Consider how missing areas in pictures would impact mapping.
3Question 3.
What does the term air-base refer to?
- Distance covered by an aircraft
- Distance between two exposure stations
- Total flight duration
Show hintHide hint
Focus on measuring distance aspects in aerial photography.
4Question 4.
True or False: A larger air-base leads to better image overlap.
- True
- False
Show hintHide hint
Consider the implications of distance on photo quality.
Question 5.
Aerial surveys require different air-base calculations for urban and rural landscapes. Discuss the necessary adjustments you would make for each situation.
Show hintHide hint
Think about how urban versus rural environments differ in structure and visibility.
Question 6.
Calculate the ideal air-base for a canyon area requiring at least 70% overlap with images covering 1 km² each. The total area is 50 km².
Show hintHide hint
Use the formula for coverage and overlap requirements to determine the air-base effectively.
