Next, compute the XIONG file. Open NIR band 5 and band 4 (panchromatic) inthis order. (For the first pass, use the default scale factor setting.) Do this byselecting ‘Pan Sharpening’ | ‘XIONG Algorithm’. In a few moments a singlegrayscale file will be displayed. This is the XIONG image. Save it in any format,naming it ‘xiong.tif’ or the like.Now HSI pan sharpen as usual (four file method) by opening band1 (blue),band2 (green), band3 (red), XIONG (processed panchromatic). The resulting pansharpened file should have more natural vegetation tones than the correspondingpan sharpened image-using bands 1, 2, 3 and panchromatic.If the vegetation is too green or not green enough, run another iteration exceptthis time check the ‘Activate Image Processing Routines’. Adjust the XIONGscale factor using the slider bar on the XIONG Input Form. The default value is50%.The following files show the results of using the XIONG algorithm on atroublesome file with lots of vegetation. The first image shows the low resolutionRGB composite image that forms the color standard.71
The next image shows the pan sharpened image with histogram matching. Notethere is still a lot of unnatural blue tint to the vegetated areas.Finally, the XIONG image. Note that the color tones match the RGB standardalmost exactly (of course this image has twice the resolution of the RGB image.)72
