Question / feature / smallest meaningful change:
Area of interest / saved polygon / coordinate system:
Image A: provider / mission / sensor / product ID / acquisition UTC:
Image B: provider / mission / sensor / product ID / acquisition UTC:
Collection / processing level / processing version:
Native pixel sizes (meters) of each band:
Cloud / cloud shadow / snow / invalid-pixel mask:
Season / sun geometry / water or tide conditions:
Bands / reflectance scale / offset:
Projection / alignment / resampling method:
Display stretch (same for both?) / numerical analysis steps:

Instructions: Separate source measurements, visual interpretation and causal
explanation. Do not treat a display screenshot or resampled image as new detail.
Example only: NDVI=(0.50-0.20)/(0.50+0.20)=0.428571. Inputs are
invented reflectances, not stored digital numbers or field measurements.
