18.4.3. Flight Parameters

Try these first

1. 1.

   What is the typical flight height range used in aerial surveying?

   Hint

   Think about the altitude generally used for drone operations.

2. 2.

   Define overlap in the context of aerial surveying.

   Hint

   Consider the extent of area reused in multiple images.

3. 3.

   What is the standard flight height range for aerial surveys?

   • 10-30 meters
   • 60-120 meters
   • 150-300 meters

   Hint

   Think about typical UAV operational altitudes.

4. 4.

   True or False: Higher GSD values are better for detail in imagery.

   • True
   • False

   Hint

   Recall how GSD affects image fidelity.

5. 5.

   If a UAV flight at 100 meters yields an image with a GSD of 5 cm, how does increasing the flight height to 150 meters impact the GSD?

   Hint

   Think about how distance affects clarity.

6. 6.

   Evaluate the effectiveness of using 75% front overlap in comparison to the standard 80%. What might be the consequence in 3D modeling?

   Hint

   Consider how images relate in reconstruction.
