Try these first

1. 1.

   What is change detection?

   Hint

   Think about monitoring changes in satellite images.

2. 2.

   Define time-series analysis.

   Hint

   Consider how you could track changes over time.

3. 3.

   What is change detection?

   • A method for monitoring seasonal changes
   • Identifying differences over time
   • A technique for enhancing image quality

   Hint

   Think about how you would measure change in anything over time.

4. 4.

   True or False: Post-classification comparison involves comparing raw satellite images.

   • True
   • False

   Hint

   Consider what classification means in the context of imagery.

5. 5.

   Design a research project utilizing change detection and time-series analysis to assess the impact of climate change on a particular ecosystem.

   Hint

   Consider which ecosystems might be most affected by climate change and the types of satellite data available.

6. 6.

   Critically analyze how the choice of change detection method might influence environmental monitoring results.

   Hint

   Predict how each method might produce different insights based on the scale and type of change observed.
