4.8.21. Superlap

Try these first

1. 1.

   What is superlap in aerial photography?

   Hint

   Think about how photographs overlap when taken from an aircraft.

2. 2.

   If each photograph has a 60% overlap, what is the superlap approximately?

   Hint

   Think of the formula for calculating superlap from overlap percentages.

3. 3.

   What is the definition of superlap?

   • The overlap between two photos
   • The overlap between three photos
   • The distance between photos

   Hint

   Think about multiple photos instead of just two.

4. 4.

   True or False: Higher superlap guarantees better image quality.

   • True
   • False

   Hint

   Consider how coverage affects data completeness.

5. 5.

   Calculate the necessary overlap percentage required to achieve a superlap of 60% using the formula for superlap based on overlaps of three photographs.

   Hint

   Think about how the cubes of overlaps relate to superlap.

6. 6.

   Discuss a scenario where superlap could both positively and negatively impact an aerial survey's efficiency. Outline the points.

   Hint

   Consider the trade-offs of efficiency vs. detail.
