Until recently, there were no standards for deriving the orthogonal rotation coefficients due to the pluralistic interpretation of the tasselled cap features (Lobser and Cohen 2007). Any number of TCTs may be developed if the choice of aligning these three axes is left to the discretion of a researcher. Since the launch of Landsat 8 in 2013, it was being demanded by researchers working on vegetation how to use TCT for this new sensor in a same way they used it for other sensors. Addressing that dire need of researchers, this study is presenting the new TCT coefficients for operational land imager (OLI) in a form of this letter. To maintain the continuity among the sensors for the same tasselled cap idea originally propounded by Kauth and Thomas (1976) and investigated by Crist with other researchers (Crist and Kauth 1986; Crist 1985; Crist and Cicone 1984b, 1984a), this study uses the Procrustes rotation (PR) transformation for deriving the TCT coefficients for OLI of Landsat 8 (Andrade et al. 2007, 2004; Lobser and Cohen 2007).
