Creating pan sharpened imagery from non-matching sources
Hi there,
I have another question re pan sharpening, but I may have made a basic misassumption re the process. I have downloaded a batch of files from Copernicus Contributing Missions, but whilst there are a number of M/S images, they do not all have matching panchromatic imagery (which I find puzzling, as I thought they ought to, given the pan sensor is on the same platform as the M/S one – but that’s another story). However, I do have a full set of sub-metre panchromatic images, but from another sensor. I assumed that I could use these to create pan sharpened images, but I can’t get them to produce anything like true colour imagery. I’ve used the ‘Environment’ setting ‘Intersection of inputs’, as I assumed that ought to just operate on the overlap between the pan and M/S data, but whilst it does find the correct extents, I get very odd outputs. I’ve tried altering the bands input from 1,2,3 to 4,3,2 etc, but nothing works.
Have I got something fundamentally wrong in my understanding of how this ought to work?
Unfortunately, as with my previous question, because these are commercial data, I can’t share them for others to test.
Thanks
