# Spectral resolution

This refers to the wavelength intervals (types of light) in which data are collected. Spectral resolution controls the information which can be derived from image data.

1. High (hyperspectral, Greater than 20, narrow spectral bands (< 20nm) )
2. Medium (multispectral, 3-20, broad spectral bands)
   Medium designed for land application (2-8 broad spectral bands (60-100 nm))
   Medium designed for coastal and Ocean water (8 to 15 broad spectral bands (5-20 nm))
3. Low (panchromatic, analog or digital images) (1 band or true or false colour with 3 to 4 spectral bands (60-100 nm)
