Abstract

The research was intended to estimate Chl-a concentration of coastal water in Liaodong Bay, China based on reflectance spectra data collected in situ and satellite hyperspectral data—Hyperion image. After processing and atmospheric correction, the reflectance of water extracted from Hyperion image can be used to express the spectral characteristics of different Chl-a concentration. Ratio calculation of reflectance between absorption and reflection peaks of Chl-a, the derivative analysis of spectrum can greatly improve the correlation with Chl-a concentration. Exponential model of Chl-a concentration with variable of band ratio between 681nm and 671nm was applied to Hyperion and the mean absolute percent error is 34% and root mean square error value is 3.30μgl^-1.
