We also compared HighView pan-sharpening results with those from traditional methods, including Brovey, IHS (Intensity-Hue-Saturation) and PCA (Principal Component Analysis), consistent, robust and superior spectral recovery was achieved in HighView. We encourage interested users to download a copy of HighView trial version and to test their own data - seeing is truly believing!
