19.12. Post-Processing Workflows

Try these first

1. 1.

   What is the purpose of image stitching in UAV data processing?

   Hint

   Think about how photos are combined into one larger picture.

2. 2.

   Define Digital Elevation Model.

   Hint

   Consider how we can model ground features.

3. 3.

   What does image stitching accomplish?

   • Creates individual images
   • Combines images
   • Removes details

   Hint

   Think about putting pieces together like a puzzle.

4. 4.

   True or False: Digital Elevation Models are used to show only building heights.

   • True
   • False

   Hint

   Consider the broader scope of ground data.

5. 5.

   A construction site needs a detailed topographic survey. The UAV images have poor lighting conditions resulting in unclear overlaps. How would you address this in post-processing?

   Hint

   Consider the importance of image quality before stitching.

6. 6.

   You have calculated the volume of a stockpile from UAV data. However, you suspect measurement inaccuracies. What steps could you take to verify precision?

   Hint

   Think about checkpoints and how they can validate measurements.
