Abstract

Spectral reconstruction is a prerequisite for quantitative analysis of hyperspectral data, and atmospheric correction is the key step to spectral reconstruction. The atmospheric radiative transfer model is the most feasible method for hyperspectral data without simultaneous measurement of the ground. In this paper, the prevalent atmospheric radiative transfer models MODTRAN4.0 and 6S were used respectively for atmospheric correction and spectral reconstruction of EO-1’s Hyperion hyperspectral data in the study areas. Then the results of the correction using the atmospheric radiative transfer model and the applicability of the model were evaluated by comparing three types of reconstructed spectra respectively from vegetation, clay mineral and water and by calculating accuracy of spectral reconstruction using the statistical method. The superiority of integrated processing is reflected in the end by the application of FLAASH model.
