The paper presents some results of vegetation spectral identification

classification and biomass mapping by hyperspectral imaging spectrometry in Poyang Lake wetland

China The study focuses on how to retrieve canopy biophysical characteristics and how to identify vegetation types from hyperspectral image effectively The main approaches are as follows ①Retrieval of apparent surface reflectance from imaging spectrometer imagery

based on Multiheigh technique;②Derivative spectral analysis and biomass estimation;③Wetland vegetation identification and classification based on spectral waveform matching
