Pansharpening is an image processing technique that enhances the spatial resolution of an image.

By fusing a highresolution black and white panchromatic image with lowerresolution color imagery, you can achieve a much sharper output image.

In this tutorial, I am going to use Landsat imagery and show you how to use pansharpening in ArcGISPro.
