Palette Resolution
Rasters containing bands with palettes can be resolved to band without palettes through a process called palette resolution. During this process each band value is looked up in the palette and the resultant value is placed in the band. Once complete, the palette is removed and the band interpretation and data type are adjusted. The resultant raster has the same appearance and values as the original, except the palette is not present. Alternatively palettes can be directly removed without the palette resolution step.
