4.31. Long questions

Try these first

1. 1.

   What is the relationship between altitude and scale in aerial photography?

   Hint

   Think about what happens visually at greater heights.

2. 2.

   Define relief displacement.

   Hint

   It affects how tall objects appear in photographs.

3. 3.

   What factors affect the scale of an aerial photograph?

   • Altitude
   • Focal Length
   • Terrain Elevation
   • All of the above

   Hint

   Consider all through AFE factors.

4. 4.

   True or False: Relief displacement is only a factor when photographing flat terrain.

   • True
   • False

   Hint

   Think of varying object heights in photographs.

5. 5.

   A photograph is taken at an elevation of 1800 m with a focal length of 75 mm over varied terrain ranging from 50 m to 300 m. Calculate the scale interval for this photograph.

   Hint

   Focus on the differences that most affect the final scale.

6. 6.

   Given that a hill's image is displaced by 5.1 cm, and the flying height was 2500 m - what is the true height of the hill?

   Hint

   Make sure all units are consistent before solving.
