I am currently working with Landsat 8 imagery and an having a hard time pan-sharpening the imagery to get a better resolution. Then option under properties>pan-sharpening to choose an infrared image as the 4th band is greyed out. I am not sure if I am going about this right. Should I create an new mosaic dataset first, then a natural color image and follow that with the pan-sharpening? Any tutorials on this would help.
Second question is, when I clip the raster image from the study area boundary, the color of the pixels changes. How do I prevent this discoloration and maintain the natural color of the pixels? My analysis is dependent upon the pixels maintaining their natural color. Any help would be appreciated.
