Table of channels, their applications and image examples
Table 2: channel number, central wavelenght, characteristics and typical applications, Abbreviations: VIS: visible, IR: infrared, NIR: near IR, MIR: middle IR, WV: Water Vapour
The fourth column of the table lists the RGB (Red-Green-Blue) combinations of different channels in which the respective channels are used. The RGB's are discussed in detail in the next chapter.
