A Study on Inland Water Quality Parameters Estimati on and Mapping Using Hyperion imagery
Water quality parameter is an important indicator to measure the productivity and eutrophication of water. The paper focuses on the estimation research of water quality parameters in Dongting Lake, based on Hyperion image which was acquired on December 28, 2010. Based on atmosphere correction and spectral features analysis, the sensitive bands and band combinations were compared with in situ spectral data. Then estimation model for chlorophyll a concentration and suspended solids concentration were built respectively, and corresponding spatial distribution features were analyzed. Results showed that the effect of Hyperion atmosphere correction was perfect, which can be used for the estimation of water quality parameters. The ratio of band 701 nm and 752nm was suitable for the inversion of chlorophyll a concentration. Mapping results of water quality parameters are reasonable and consistent with the natural distribution rules. The research reveals the potential of Hyperion image on the inland water monitoring, which contributes to the accurate estimation of water quality parameter monitoring.
