Abstract

Hyperspectral Remote sensing is a new synthetical probing technology in recent ten years,which is successfully used in the fields of geology investigation and vegetation in research.But in the filed of supervision and forecast of red tide ,its application is in the stage of experiment.In this article,we abstract the waveform of the spectra of the red tide area and the no red tide area from the Hyperspectral data,and calculate the spectral absorbed characteristic parameters including:the position,depth,wide,symmetry and area of the wavelength of the absorbed band.Constrast the result and use the spectral differential technology,we will get the two kinds of sea surfaces and analyse them protiminary.
