Paper Abstract

Band sharpening involving multi-sensor and multi-resolution imagery is an excellent means of utilizing the complementary nature of various data types. The synergistic use of these imagery types can provide additional information that is not independently available in each source. In the case of band sharpening, a higher spatial resolution panchromatic image is fused with a lower spatial resolution multispectral image. This fusion creates a product with the spectral characteristics of the multispectral image and a spatial resolution approaching that of the panchromatic image. The goal of this project was to evaluate MSI band sharpening in four research areas. The first area explored the 'effective ground sample distance' and relative utility of multispectral imagery sharpened with panchromatic imagery. The second area examined interactions between data compression and the band sharpening process. The third area determined the effectiveness of band sharpening using a pair of high resolution sharpening bands covering different regions of the electromagnetic spectrum. The fourth area determined the effect of band sharpening on the accuracy of automated exploitation algorithms such as terrain categorization and normalized difference vegetation index.
