4.8.37. Swing

Try these first

1. 1.

   Define the term 'swing' in photogrammetry.

   Hint

   Think of it as how much the photograph is rotated.

2. 2.

   Explain why it's important to control swing during aerial photography.

   Hint

   Consider the implications of distorted images on map reliability.

3. 3.

   What is swing in aerial photogrammetry?

   • The angle to the principal line
   • The type of camera used
   • The height of the aircraft

   Hint

   Focus on the definitions of key terms.

4. 4.

   True or False: Swing has no effect on the outcome of aerial photographs.

   • True
   • False

   Hint

   Recall how photographs need to be aligned for proper data collection.

5. 5.

   Given a photograph with a swing of 75 degrees, calculate how this affects the principal point's interpretation versus a swing of 10 degrees.

   Hint

   Consider how angle changes would shift the view of the image.

6. 6.

   Evaluate a scenario where an aircraft experiences severe yaw causing swing discrepancies during a photogrammetric survey. Discuss how to adjust parameters for future flights.

   Hint

   Reflect on the implications of aerial stability measures.
