An instrument capability using many very narrow spectral frequency bands (300 or more), enabling a satellite-based passive sensor to discriminate specific features or phenomena on the body being observed (such as Earth)
The term hyperspectral is a remote sensing term denoting a sensor system observing a target in hundreds of spectral bands. The high sampling of the spectrum provides a great increase in information. The wavelengths and resolution would depend on the choice of sensor and the application.
