SPOT products differ by pixel size (ground sample distance of 2.5 m, 5 m, 10 m or 20 m) and spectral acquisition mode (black and white or colour).
Resolution and Spectral Bands
They correspond to:
- a view of part of the Earth taken in one or more spectral bands with a given spatial resolution;
- or the merging of two separate images acquired at the same time, one being in black and white and the other, colour.
