Time Series

Purpose

Introduce multi-date imagery as a way to observe change, seasonality, and disturbance through time.

Outline

• Image dates, acquisition frequency, and observation gaps
• Seasonal cycles, trends, and abrupt events
• Composites, summaries, and temporal windows
• Noise from clouds, shadows, sensor differences, and viewing geometry
• Interpreting time series with domain context

Later Examples

• Plotting a vegetation signal through a growing season
• Comparing monthly and annual summaries
• Finding dates before and after a disturbance
