Summary:Due to the high spatial and spectral resolution, hyperspectral data have attracted many researchers' attention. Field Imaging Spectrometer System (FISS) is a newly hyperspectral sensor with high quality spectra in visible bands. But the spectral reflectance in near-infrared band is much lower than the normal spectra. In order to calibrate the FISS image data, the ASD spectra of locust leaves are applied to PROSAIL model for validation. By dividing the data into two parts, the visible band and near-infrared band, the parameters of PROSAIL model are obtained by finding the best match of visible band. Then, the parameters are applied to the near-infrared band for validation and thus applying the method to FISS image data for calibration. The results show that this method can calibrate the data effectively and make the data more practical.
