Spectral enhancement is the process of creating new spectral data from available bands. Spectral enhancement techniques are typically used to extract data that is more interpretable to the eye and more appropriate for analysis.

In this video, I covered the Spectral enhancement of satellite imagery using various methods in ArcMap. I also looked at the options available for changing display in the image analysis window.
