ABSTRACT
Few decades ago hyperspectral imagery data and processing software were available to only spectral remote sensing experts. Nowadays, the research and development of hyperspectral sensors for data acquisition and the associated software for data analysis is one of the fastest growing technologies in the œeld of remote sensing [1]. Unlike multispectral imaging systems (e.g., Landsat, SPOT, IKONOS type) that capture reŸected or emitted incoming from the Earth’s surface in a few broad wavelength bands across the electromagnetic spectrum, hyperspectral imagers (HSI) measure reŸected radiation at numerous narrow, contiguous wavelength channels. The substantially œner spectral resolution data from hyperspectral sensors enhance the capability to characterize the Earth’s surface more effectively than do the broadband multispectral data [2].
