Abstract

In Situ hyperspectral data analysis for varied coverage estimation of submerged plant is very important for the interpretation of remote sensing images. In this study, the hyperspectral reflectance of Vallisneria spiralis was measured using a Spectroradiometer with spectral range of 350-1050 nm and resolution of 3 nm in Hangzhou bay wetland and the cover of submerged plant was measured. The results showed that the reflectance rate and the "red edge peak" of the first derivation of Vallisneria spiralis spectrum rose with its increasing coverage. The relationships between the coverage of Vallisneria spiralis and the spectral reflectance, spectral indices and red edge at the wavelengths were carried out and analyzed respectively. These results showed a clear linear relationship between the coverage of Vallisneria spiralis and spectrum, and the coverage of Vallisneria spiralis could be quantitatively estimated from the reflectance measured in situ. The hyperspectral remote sensing have a ability and potential to distinguish and monitor the distribution and dynamics of submerged vegetation on a large scale.
