What is spectral resolution?

Spectral resolution refers to how many different wavelengths of light or other emissions that a satellite can detect.

For instance a low spectral resolution satellite might only collect one band or colour of information.

In terms of film or digital cameras, you might think of a black and white camera as being a low spectral resolution sensor.

and a colour camera as being a medium or higher spectral resolution camera.

At the very high end of spectral resolution you have what's called hyperspectral cameras or sensors which can detect sometimes tens or hundreds of wavelengths of light and can measure exactly within each wavelength and give you a very accurate picture of what you're looking at.
