I again selected ‘Close Graphic Images and Reset’. Both subset scenes had 578Rows and 702 columns with the same corner coordinates and of course thesame scale so no further processing was necessary.Since 78% of the ‘A’ scene would be output as compared to only 22% of the ‘B’scene (no gap) I wanted to get the pan sharpening parameters correct for the ‘A’scene. To do this I pan sharpened bands 1, 2 and 3 with the panchromatic bandusing the HSI algorithm. I first generated the 30m RGB rendering for referenceby opening bands 1, 2 and 3. I checked the ‘Maintain RGB Comparison Image’so that the 30m RGB band rendering would be maintained during subsequentpan sharpening. I then selected ‘Band Combination’ | ‘Generate True RGB ColorComposite’. Then I selected ‘Close Graphic Images and Reset’.Now for the pan sharpening. I opened bands 1, 2, 3 and the panchromaticsubset bands. I then selected ‘Pan Sharpening’ | ‘HSI Transform’ | ‘StandardFour File’. I accepted the default iterations. The pan sharpened image wascomputed. The 30m RGB color composite and the pan sharpened images areshown below. (The pan sharpened image is shown at half-scale).360
