Calibration of Aviris Remote Sensing Data from Poyang Lake Area

Three different calibration models were intensivly studied and applied in the calibration of airborne imaging spectrometer(AIS) remote sensing data acquired from Poyang Lake area in december,1995.The calibration study results demonstrate that the empirical calibration model is the best model among the three models.The retrieval spectral results from the empirical Calibration model are correspond to the measured filed spectra very well.How-ever,the deficiency of the empirical model is that the calibration sites must be selected carefully.Sometimes,it is not convenient.
