8.14.3. Flight Planning Essentials

Try these first

1. 1.

   Define forward overlap in UAV flight.

   Hint

   Think about how images overlap while moving in a straight line.

2. 2.

   What is the typical range of side overlaps?

   Hint

   Consider how much images need to overlap from adjacent flights.

3. 3.

   What is the typical forward overlap percentage required for UAV imagery?

   • 40-50%
   • 60-80%
   • 20-30%

   Hint

   Think about how overlaps help in modeling.

4. 4.

   True or False: Higher flight altitude results in a lower Ground Sampling Distance (GSD).

   • True
   • False

   Hint

   Consider how altitude and detail relate.

5. 5.

   You are tasked with creating a 3D model of a coastal area using UAVs. How would you determine the best flight altitude and overlaps for this project? Consider environmental factors as well.

   Hint

   Consider the trade-off between detail and coverage in your planning.

6. 6.

   Discuss the potential risks and benefits of flying drones over urban environments compared to rural areas. What flight planning considerations would change?

   Hint

   Think about the differences in setting and regulations.
