http://bleutner.github.io/RStoolbox/rstbx-docu/sam.html WebThe spectral angle mapper (SAM) is physically based spectral classification that uses an n -dimensional angle to match pixels to reference spectra. The algorithm determines the spectral similarity between two spectra by calculating the angle between the spectra by treating them as vectors in a space with dimensionality equal to the number of bands.
