Press ‘OK’. The transformed grayscale band will be computed and displayed.Save it as a GeoTiff file. I used the base file name ‘processedImage1’.What we have done is to create a linear equation that maps the three raw pansharpened band to the source blue band. In other words, the equation defineshow much of the raw blue, green and red bands must be combined in order tomake the blue band. Because the coefficients are the result of a regression, themapping will not be exact for each pixel. But hopefully the mapping will be closeenough in order to produce an improved pan sharpened band, and thus animproved pan sharpened image.Repeat the procedure above for the second Landsat multispectral band (i.e. thegreen band). That is, open the green band and the three resized raw pansharpened bands. Compute the next set of coefficients and then transform theraw pan sharpened green band. Finally, repeat the procedure for the red band.The only step left is to create an RGB color composite using the processed pansharpened bands. Select ‘Band Combination’ | ‘Generate RGB True ColorComposite’. The result of my efforts is shown below.380
