4.8.1. Exposure Station

Try these first

1. 1.

   What is an exposure station?

   Hint

   Think about the position of the aircraft.

2. 2.

   Why is overlap important in aerial photography?

   Hint

   How do different photographs work together?

3. 3.

   What is the main function of an exposure station?

   • To capture images
   • To store data
   • To analyze photos

   Hint

   What does it literally refer to?

4. 4.

   True or False: The perspective center is the location of the exposure station.

   • True
   • False

   Hint

   Think about how images are formed.

5. 5.

   If an aerial survey is conducted with a flying height of 1000 meters and a camera with a focal length of 50 mm, calculate the scale of the photograph. Discuss how this scale might change if the flying height increased to 1500 meters.

   Hint

   Remember that increasing flying height decreases the scale.

6. 6.

   Discuss how improper overlap due to incorrect exposure station planning can affect the mapping of a forest area. Provide potential strategies to mitigate these issues.

   Hint

   Think about why continuous coverage is necessary in forest mapping.
