4.8.3. Perspective centre

Try these first

1. 1.

   What is a perspective centre in aerial photography?

   Hint

   Think of the center from which all photo rays emanate.

2. 2.

   What does relief displacement refer to?

   Hint

   Consider how taller buildings might shift in a photo.

3. 3.

   Which of the following describes the perspective centre in aerial photography?

   • A point where some light rays meet on the ground
   • A point where all projecting light rays converge
   • A point that has no relation to the photograph

   Hint

   Think about how light works in photographs.

4. 4.

   True or False: Relief displacement is not important when calculating areas in urban planning.

   • True
   • False

   Hint

   Consider the implications of incorrect measurements on planning.

5. 5.

   How would ignoring the perspective centre affect measurements in a forest management scenario? Provide an example.

   Hint

   Consider the practical consequences of errors in resource planning.

6. 6.

   Design an experiment to demonstrate the effects of relief displacement using varying heights on images. Outline materials and expected results.

   Hint

   Think about how you might visually show the impact through actual photographs.
