Table 3. Signature separability between land-cover classes used in the supervised classification. Values are calculated as the statistical difference between parts of spectral signatures using Bhattacharrya Distance methods. A value of 0 indicates a complete overlap in the spectral signature between the two classes and a value of 2 indicates complete separation. Habitat type numbers across the top match those on the side.
