18.1.3. Key Components of an Aerial Surveying System

Try these first

1. 1.

   What does UAV stand for?

   Hint

   Think of the type of aircraft used without a pilot.

2. 2.

   What is the primary function of a GPS in aerial surveying?

   Hint

   It helps to find exact positions.

3. 3.

   What is the main purpose of a UAV in aerial surveying?

   • To transport goods
   • To capture aerial data
   • To provide GPS coordinates

   Hint

   Think about what these vehicles are typically used for in surveys.

4. 4.

   True or False: LiDAR is less effective than traditional cameras in dense areas.

   • True
   • False

   Hint

   Consider what each technology excels at.

5. 5.

   Design a survey plan for mapping a dense forest using both UAV and LiDAR technology. Include details on how GCPs would be integrated into the process.

   Hint

   Consider visibility and accessibility for setting GCPs.

6. 6.

   Critically evaluate the differences between using a standard camera and a LiDAR sensor in an aerial survey of an urban area. Discuss the advantages and disadvantages of each.

   Hint

   Think about the types of data you want from the survey.
