Fusion of multisensor imaging data enables a synergetic interpretation of complementary information obtained by sensors of different spectral ranges (from the visible to the microwave) and/or with different number, position, and width of spectral bands (Richards, 1999) (Minghelli-Roman, 1999) (Minghelli-Roman and al., 2001).

 

Resolution merging combines data of different spatial resolutions to get some of the advantages of higher spatial resolution while retaining some of the spectral information.
