1. 1.

   What is change detection in photogrammetry?

   Hint

   Think about monitoring changes over time!

2. 2.

   Define Digital Elevation Model (DEM).

   Hint

   What does it depict about the landscape?

3. 3.

   What are time-series orthomosaics used for?

   • Tracking finance
   • Monitoring changes
   • Measuring distances

   Hint

   Think about what 'time-series' means.

4. 4.

   True or False: Slope analysis helps improve erosion control in watershed management.

   • True
   • False

   Hint

   What role does slope play in water movement?

5. 5.

   How would you implement change detection using time-series orthomosaics in a real-world scenario? Describe a step-by-step process.

   Hint

   Consider tools and what type of changes you are interested in.

6. 6.

   Given a case study of a watershed experiencing increased erosion, propose how slope analysis from DEMs could inform conservation strategies.

   Hint

   Think about how landform affects how water runs off.
