4. 4.

   LiDAR is particularly beneficial because it can penetrate vegetation.

   • True
   • False

   Hint

   Consider how traditional surveying methods might operate in vegetation-heavy areas.

5. 5.

   Consider a situation where LiDAR is used over a dense forest. Discuss specific advantages and potential limitations. What factors might affect the accuracy of the data collected?

   Hint

   Think through how different obstacles might interfere with laser detection.

6. 6.

   Design a mini-project where LiDAR data would improve a specific civil engineering task. What kind of data would you gather, and how would it aid project decisions?

   Hint

   Consider how elevation data could influence planning for safety.
