Applying pan-sharpening to a raster layer in ArcMap

  1. In ArcMap, add the lower-resolution color image to the map using the Add Data button Add Data.
  2. Right-click the raster layer in the table of contents and click Properties.
  3. Click the Symbology tab.
  4. Click RGB Composite on the Show menu.
  5. Scroll to the bottom of the Properties list and check Pan-sharpening.
  6. Click the Panchromatic Image drop-down arrow and click an image name or click the browse button Browse and select the higher-resolution image.
  7. Click the Pan-sharpening Type drop-down list and choose the desired color transformation.

    • Brovey
    • ESRI
    • Simple Mean
  8. Optionally, type a weight value for each of the red, green, blue, and infrared bands.

    These values should sum to 1.

  9. Optionally, if the fourth band of your raster dataset is the infrared band and you want to use it, then you need to check the 4th-band as Infrared Image check box.
  10. Click OK.

It is a good idea to set the display resampling to bilinear interpolation. It will make the output pan-sharpened image less pixelated. The display resampling can be accessed on the Layer Properties dialog box, under the Display tab.
