The MCE coordinates were still retained. I saved these files as ‘MCAB’. Finally,I subsetted the band 50 files singly, still using the retained MCE coordinates. Inow have two sets of six band files each with the same corner coordinates,scales and row and column counts (the panchromatic rows and columns aredouble the band file counts and the scales are 15m per pixel rather than 30m perpixel of the band files.)The next step is gap filling. This is done exactly as described for the smallsubset files, starting with the six file method selecting ‘Gap Fill’ | ‘Gap Fill HayesInterpolation Method’ | ‘Six File Set’. (This computation will take a while). At thecompletion of the run I saved the files, and then gap filled the panchromaticbands and bands 40 and 50 pair wise as before.The final step was to compute the full sized RGB composite and pan sharpenedimages. This was done exactly as before, except using the full sized gap filledimages instead of the small subset images. A complete set of the entire examplefiles for this exercise, plus the output images are available for download from thePANCROMA TM customer ftp site. If you are interested in obtaining access tothese files, please email me at jchilds@terrainmap.com.This file set was not very well matched, and presented a lot of processing issues.The major take-away from the exercise is that it pays to spend more time upfront obtaining as close a match of the gap and no-gap images as possible. Thetechniques I used for this example are not the only ones that could have beenused. Hopefully however, this Tutorial gave you some ideas aboutPANCROMA TM satellite image processing capabilities.375
