4.8.6. Flight Strip

Try these first

1. 1.

   What is a flight strip?

   Hint

   Think about how aircraft capture photos during their flight.

2. 2.

   Why is overlap important in aerial photography?

   Hint

   Consider how images are combined to see depth.

3. 3.

   What does a flight strip represent in aerial photography?

   • A single photo
   • A corridor of ground area covered by a flight line
   • An altitude range

   Hint

   Think about what area an aircraft captures.

4. 4.

   True or False: Overlapping flight strips are necessary for creating 3D models.

   • True
   • False

   Hint

   How do you create depth in images?

5. 5.

   Aerial surveys conducted over a rectangular area require 4 flight lines. If each flight strip has a width of 50 meters, and the total area to cover is 600 meters wide, does this configuration leave any gap?

   Hint

   Calculate the total coverage and compare to the area size.

6. 6.

   During an aerial survey, data shows that terrain has varying ground elevations. How would this influence the flight strip method used, and what corrections might be necessary for effective mapping?

   Hint

   Consider how height changes may alter what is visible in photographs.
