High spectral resolution is the main characteristic of hyperspectral remote sensing. The image of objects includes various
information of space, radiation and spectral information, and we can also construct a continuous spectrum curve in the
imaging range. The purpose of topographic correction is to eliminate the effects of solar light , which may make the
spectral curve not accurate compared with the practical curve, on radiation values of irregular ground object.
This paper is to analysis the advantages and disadvantages of various topographic correction methods, and provide
accurate experimental data for quantitative remote sensing, which based on the area of airborne hyperspectral remote
sensing image and DEM, comparing with the measured spectral curve.
