Numerous Pansharpening Algorithm has been developed. Some of them are better in preserve the spatial details of the panchromatic band but have poor spectral information preservation of multispectral bands, and vice versa. ArcGIS has implemented some of the most wellknown PanSharpening algorithms into its roster of geospatial tools. Some are good, some are good only in certain aspects.

Fortunately, Pan Sharpening implementation in ArcGIS also complemented with a weighting factor. These weights value can be derived from the datadriven approach. By using these weights, we can further control the PanSharpening algorithm that has poor ability to maintain spectral information like IHS to be more consistent with the multispectral bands. And this is what the video is about.
