Use images to analyze change.

Use should involve a series of aerial or satellite images of the same location to evaluate changes over time. Use could include development of indices (e.g., burning index, normalized difference vegetation index [NDVI]).

Process/Skill Questions:

• How can images taken at different times (temporal scale) be used to detect changes in the environment?
• What are reasons to compare images of the same location taken at different times?
• How can this method be used to monitor urban development?
