摘要
The atmospheric correction is prerequisite to derive both land and ocean surface properties from satellite remote sensing data. It also improves the satellite image quality and the performance of value-added image processing. The purpose of this study is to develop an image-based atmospheric correction method for the forthcoming Korea Multi-Purpose SATellite-2 (KOMPSAT-2) Multi-Spectral Camera (MSC) data. For this purpose, we have first tested the several atmospheric correction models using the Landsat Enhanced Thermal Mapper Plus (ETM+) data that have quite similar spectral characteristics to the KOMPSAT-2 MSC data, and the in situ measured sin-face reflectance data during the satellite overflight. Subsequently, we have applied the selected models to the IKONOS data with off-nadir viewing corrections because most passes of KOMPSAT-2 are subject to such viewing conditions. This presentation discusses the results of the above tests.
