Info

The Red Cutoff, Blue Cutoff and Red Adjust track bars appear in the left datagroup. This set addresses the inherent lack of red tone in the non-vegetatedareas. PANCROMA TM will increase the red DN value by the amount indicated onthe Red Adjust track bar. This amount will be added only to pixels with red DNsabove the Red Cutoff value and below the Blue Cutoff value.The second adjustment in the left data group is the Ocean Cutoff track bar.PANCROMA TM will zero the red and green DN values for all pixels with a red DNless than the Ocean Cutoff value. This serves to mask the ocean areas thatwould otherwise have a green tone if these pixels were not thus processed.The right data group simply has Red, Green and Blue adjust track bars. TheDNs of these channels will be incremented or decremented according to thevalues on the track bars. The default settings are 8, 8, and 0 for Red, Green andBlue, respectively. A processed section of the above GEOCOVER file is shownbelow.115
GEOCOVER can offer a very attractive option to standard pan sharpenedLandsat scenes, and can provide an ideal data set for preparing maps or earthmosaics.116
