Paper Abstract

During December 20 - 28, 1995, an Airborne Imaging Spectrometer (AIS, 30 bands, spectral resolution 20 nm) was flown to investigate Poyang Lake area, a famous wetland, in China. The ground spectra of various materials were also collected from the area at the same time. All the data acquired from this area were used to conduct a comparative study of different calibrations for image data. In this paper, three different calibration models were intensively studied and applied in the calibration of AIS remote sensing data acquired from Poyang Lake area. The advantage and drawbacks of the three calibrate models have been analyzed and examined. The calibrated results made by authors have demonstrated that the Empirical Linear (EL) calibration model is the best model among the three model. The retrieved spectral results of soils and vegetation from the EL calibration model were correspond field spectra very well. However, authors also found the deficiency of the EL model was that the calibration sites had to selected carefully, its choice had an important effect on the quality of retrieval results.
