It is known as the Tasseled Cap transformation due to the shape of the graphical distribution of data. The transformation provided a rationale for the patterns found in Landsat MSS data of agricultural fields as a function of the life cycle of the crop. Essentially, as crops grow from seed to maturity, there is a net increase in near-infrared and decrease in red reflectance based on soil color
