Description
Red-Edge Position Linear Interpolation (REP) is a spectral index that detects the red-edge position through linear interpolation. The red-edge position is a key indicator of vegetation health, chlorophyll content, and plant stress, representing the inflection point between red absorption and NIR reflectance.
