Gram-Schmidt Pan Sharpening in ArcGIS

When I first made this blog, I wrote few articles about Panchromatic Sharpening (Pan Sharpening). This article is also can be considered as one of them. In this article, I will share about Gram-Schmidt Pan Sharpening Method. Since a few years ago, Gram Schmidt Pan Sharpening Algorithm has been implemented in ENVI Software, and it becomes one of the best Pan Sharpening methods that could not only preserve spatial details of the Panchromatic band but also maintain the spectral fidelity of multispectral bands. 

The goodness is, this algorithm now is also has been implemented in ArcGIS. So finally we can perform a decent Pan Sharpening operation in GIS Software. This will reduce multiple software operations when we need pan-sharpened data. So finally it would be more effective for us, GIS analyst. I won't explain the technical aspect of the algorithm because there are many articles on the internet that already talks about it. I only want to share how to perform pan sharpening using Gram-Schmidt Algorithm in ArcGIS through a video tutorial below.
