18.5. Data Acquisition Techniques

Try these first

1. 1.

   What is a geotagged image?

   Hint

   Think about what information is embedded in the image.

2. 2.

   What does LiDAR stand for?

   Hint

   Remember the laser technology used for distance measurement.

3. 3.

   What is the main purpose of capturing geotagged images in aerial surveying?

   • To create artistic photos
   • To ensure accuracy in mapping
   • To reduce flight time

   Hint

   Think about the role of location in surveys.

4. 4.

   True or False: LiDAR can only be used to capture visible spectrum data.

   • True
   • False

   Hint

   Consider what types of data LiDAR can provide.

5. 5.

   Imagine you are a project manager overseeing an aerial survey for a new highway. Describe how you would design a data management protocol to ensure successful project outcomes.

   Hint

   Consider all stages of data handling from collection to analysis.

6. 6.

   Analyze how variations in environmental conditions during a survey could impact the accuracy of image capture and LiDAR data.

   Hint

   Think about practical examples of how weather impacts survey techniques.
