• Multiplicative is based on simple arithmetic
  integration of the two raster sets.
• The Principal Components merge operates on PC-1
  rather than the input raster image.
•  In the Brovey Transform option, all bands are
  used according to the following formula
• DNB1 / DNB1 DNB2 DNBn x DNhigh res.

• DNB2 / DNB1 DNB2 DNBn x DNhigh res.
