Abstract :
The EO-1 satellite consist of three imaging sensors including Hyperion, which is currently the only space-borne HSI data source. The unique capability of hyperspectral sensing for coastal characterization provides the possibility for exploring the coupled effects of coastal features and a more accurate atmospheric compensation. It is illustrated in this paper that hyperspectral data inherently provide more information for feature extraction than multispectral data despite Hyperion having a relatively low SNR. Chlorophyll retrievals are obtained from Hyperion data and the results compare favorably with data from other sources. The analysis illustrates the potential value of Hyperion (and HSI in general) data to coastal characterization.
