Tasseled Cap Transformation
Kauth-Thomas tasseled cap transformation (TCT) uses a combination of image bands and a specialize coefficient matrix to create data plots. It is called the tasseled cap transformation because of the cap shape of the plot of values for greenness and brightness.

> Derivation of a tasselled cap transformation based on Landsat 8 at-satellite reflectance (2014)
Raster creation formula = (Band 2 coefficient*Band 2) + (Band 3 coefficient*Band 3) + (Band 4 coefficient*Band 4) + (Band 5 coefficient*Band 5) + (Band 6 coefficient*Band 6) + (Band 7 coefficient*Band 7)
