Indexes derived from the multispectral visible and near infrared bands. The wavelengths used in the formulation of the indexes are adapted slightly based on the multispectral micro-MCA Tetracam camera. * Note that for the PRI index, B550 is used instead of the original B531 by the cited reference study.
