Red-Edge

Wavelength: 0.705-0.745µm
"The red-edge band is between the near infrared and red band. For chlorophyll, the red portion strongly absorbs light while the near infrared generates a strong reflection. In the transition between these two spectral bands is the red-edge band." (GISGeography.com, 2018)
