Compare two scenes with explicit settings
- Dated scene
- Identify the displayed observation.
- Visualization
- Identify selected bands or index.
- Fix area, collection and search period.
- Record cloud cover and chosen visualization.
- Compare scenes while preserving those settings.
Fictional example: Nina examines a plot on two dates. One view contains clouds and uses an index; the other uses a different colour composition. She aligns settings before discussing a change; colour alone does not describe ground conditions.
Your useful record: Area, collection, dates, cloud filter and visualization.
A cloud filter does not automatically interpret ground conditions.
