Operation:

supervised_radiometric_geometric - The algorithm is a combined radiometric/geometric reclassification method which is called "SMAP - sequential maximum a posteriori - estimation". This method uses an image pyramid approach which also takes neighborhood similarities into account (Schowengerdt, 1997:107, see also Ripley, 1996:167-168). The module also accepts a single channel data.
