Pan sharpening uses a higher-resolution panchromatic image (or raster band) to fuse with a lower-resolution multiband raster dataset. The result produces a multiband raster dataset with the resolution of the panchromatic raster, where the two rasters fully overlap.
Pan sharpening is a radiometric transformation available through a raster function or from a geoprocessing tool. Several image companies provide low-resolution, multiband images and higher-resolution, panchromatic images of the same scenes. This process is used to increase the spatial resolution and provide a better visualization of a multiband image using the high-resolution, single-band image.
