Applying pan-sharpening to a raster layer in ArcMap
- In ArcMap, add the lower-resolution color image to the map using the Add Data button .
- Right-click the raster layer in the table of contents and click Properties.
- Click the Symbology tab.
- Click RGB Composite on the Show menu.
- Scroll to the bottom of the Properties list and check Pan-sharpening.
- Click the Panchromatic Image drop-down arrow and click an image name or click the browse button and select the higher-resolution image.
Click the Pan-sharpening Type drop-down list and choose the desired color transformation.
- Simple Mean
Optionally, type a weight value for each of the red, green, blue, and infrared bands.
These values should sum to 1.
- 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.
- 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.
