Polarimetric attributes

The predefined polarimetric attributes described in the following table are available for fully polarimetric images only (matrix type = [s4c]). The attributes correspond to a selection of parameters from various polarimetric decompositions that have the potential to discriminate among a diverse set of land-cover classes.

Note: For more information about polarimetric attributes, in the following table, click Help book to view the help of the algorithm according to the relevant programming environment.
