   What does UAV stand for?

   Hint

   Think about what kind of vehicle needs no pilot.

2. 2.

   Name one output generated from aerial surveying.

   Hint

   Consider what types of visuals help in mapping and elevations.

3. 3.

   What technology uses laser light to measure distances for mapping?

   • Photogrammetry
   • LiDAR
   • Orthophoto

   Hint

   Think about what light-based technology does.

   • True
   • False

   Hint

   Consider how UAVs can still gather data despite tree coverage.

   How would you design a UAV flight plan using photogrammetry for a mountainous area to ensure accurate mapping?

   Hint

   Consider flight altitude and overlap percentages.

6. 6.

   Discuss the implications of using LiDAR versus photogrammetry in an urban setting. Which would provide better data and why?

   Hint

   Think about obstacles in urban landscapes.
