4.8.2. Air-base or Camera base

Try these first

1. 1.

   Define air-base in the context of aerial photography.

   Hint

   Think about how photography needs spatial arrangements for clarity.

2. 2.

   Why is overlap necessary in aerial photographs?

   Hint

   Consider how missing areas in pictures would impact mapping.

3. 3.

   What does the term air-base refer to?

   • Distance covered by an aircraft
   • Distance between two exposure stations
   • Total flight duration

   Hint

   Focus on measuring distance aspects in aerial photography.

4. 4.

   True or False: A larger air-base leads to better image overlap.

   • True
   • False

   Hint

   Consider the implications of distance on photo quality.

5. 5.

   Aerial surveys require different air-base calculations for urban and rural landscapes. Discuss the necessary adjustments you would make for each situation.

   Hint

   Think about how urban versus rural environments differ in structure and visibility.

6. 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.

   Hint

   Use the formula for coverage and overlap requirements to determine the air-base effectively.
