Abstract
This paper describes a research project evaluating the success of spatially sharpening spaceborne hyperspectral imagery with higher spatial resolution spaceborne multispectral imagery. In November 2001, NASA launched its first operational hyperspectral sensor, Hyperion, on the Earth Observing-1 spacecraft. Designed to study the utility of hyperspectral imagery collected from a space-based platform, Hyperion’s utility is limited for certain applications by its spatial resolution. Successful spatial sharpening of Hyperion imagery with higher spatial resolution spaceborne multispectral imagery such as ASTER or QuickBird should further enhance the value of Hyperion imagery. In a previous two-year research initiative, the primary author demonstrated the utility of sharpening airborne hyperspectral imagery with higher spatial resolution airborne multispectral imagery. In its first year, that study simulated the sharpening process by utilizing a single airborne hyperspectral dataset to derive both a lower spatial resolution hyperspectral cube and a higher spatial resolution multispectral dataset. In its second year, this study utilized two airborne spectral collections on different platforms for the hyperspectral and multispectral datasets, and successfully demonstrated spatial sharpening despite geometry differences between the two platforms. The next logical step is to validate spatial sharpening of space-based hyperspectral imagery using higher resolution spaceborne multispectral imagery. This current research project evaluated the spatial and spectral utility of Hyperion imagery after sharpening with higher spatial resolution spaceborne multispectral data from the ASTER or QuickBird satellites.
