NDVI is a well established vegetation index that takes advantage of the relatively unique spectral qualities of vegetation, in that it absorbs large amounts of red light and reflects large amounts of infrared. It is the normalized difference of a sensor's near infrared band and its red band. There are numerous band combinations available to highlight certain materials within a scene. Here is a link describing some additional indices: http://www.harrisgeospatial.com/docs/AlphabeticalListSpectralIndices.html http://www.harrisgeospatial.com/docs/AlphabeticalListSpectra... Additionally, here is a brief description of different individual bands and how they can be used: https://gisgeography.com/spectral-signature/ https://gisgeography.com/spectral-signature/
