Abstract: Present study consists the potential of the satellite hyperspectral data — Hyperion image for mapping total suspended solids (TSS) concentration of coastal water in Liaodong Bay, China. After processing and atmospheric correction, the reflectance of water extracted from Hyperion image can be used to express the spectral characteristics of different TSS concentration. Estimated algorithms of TSS concentration based on water reflective spectra data collected in situ. The results indicated near infrared wavelength had better correlation with TSS concentration. Exponential algorithm was found to have better accuracy in estimate the concentration less than 200mg l-1 and linear algorithm was suited for the concentration range in 200–500 mg l-1 and logarithm algorithm can better describe the correlation between the reflectance and concentration range in 500–1000 mg l-1.
