Atmospheric Correction of the Hyperion Imagery for Turbid Estuary Water

Atmospheric correction of Hyperion imagery over aquatic environments is generally more demanding than over land because the signal from the water column is small. In this paper, an atmospheric correction algorithm designed for the Hyperion hyper spectral imagery based on the analysis of the atmospheric correction algorithm of FLAASH and the algorithm adopted by MODIS imagery. It makes use of band 111 and band 149 of the Hyperion hyper-spectral imagery to obtain the type of aerosol, then applied it to the near-infrared and visible light wave bands, thereby the atmospheric correction of the whole imagery is realized. The Hyperion hyper-spectral imagery applied the algorithm referred above is suitable to monitor the turbid estuary water.
