4.8.5. Flight line

Try these first

1. 1.

   What is a flight line in photogrammetry?

   Hint

   Think about the route taken by a car, but in the air.

2. 2.

   Define exposure station.

   Hint

   Where is the aircraft at the moment of capturing the image?

3. 3.

   What is the role of the air-base in aerial photography?

   • To maintain altitude
   • To measure ground distance
   • The distance between exposure stations

   Hint

   Think about how photographers ensure they have overlapping images.

4. 4.

   True or False: Overlapping photos can create 3D models.

   • True
   • False

   Hint

   Consider how your eyes perceive depth when looking at images.

5. 5.

   Design a flight path for a rectangular area of 2000m x 1500m considering a scale of 1:5000. Calculate the number of required photographs if overlap requirements of 60% end overlap and 30% side overlap.

   Hint

   Break it down: find total coverage first.

6. 6.

   Determine how a shift in wind direction may affect your flight lines and overall photographic outcome, offering examples of adjustments.

   Hint

   Think about navigation and safety measures to keep your path steady.
