From UNB PanSharp to Fuze Go – the success behind the pan-sharpening algorithm

The pan-sharpening algorithm, known as UNB PanSharp, was adopted by PCI Geomatics in 2002 and by DigitalGlobe (DG) in 2003, resulting in PCI PanSharp and DG PanSharp. Now, UNB PanSharp is developed as a stand-alone software tool, named Fuze Go™, that can be used stand-alone, integrated into ENVI and potentially into other major geo-spatial software packages such as EDARS, ESRI, and SOCET. In addition, it is in the process to integrate Fuze Go into GeoMarketSpace – a new online system that turns all geospatial information into answers. What has made UNB PanSharp successful for the last 10 years and still standing out from millions of research publications in the area? This article will go through the general principles of individual pan-sharpening algorithms that have been adopted by industry and widely used by users globally to find out the differences between UNB PanSharp and the other pan-sharpening algorithms.
