| 摘 要： | 利用FLAASH和ATCOR2模型对漓江流域的Landsat ETM+数据进行大气校正,以GLS(Global Land Survey)获得的同步高质量地表反射率影像作为参考数据,从目视效果、典型地物光谱特征和波谱一致性三方面对两种模型的校正结果进行对比分析。研究表明,两种模型均可以对ETM+影像进行有效的大气校正,FLAASH模型的校正精度优于ATCOR2模型。

| Abstract: | FLAASH and ATCOR2 models were used for atmospheric correction of Landsat ETM ＋ data in lijiang river basin, with GLS （ Global Land Survey） for synchronous high quality surface reflectance image as a reference data, and calibration results were analyzed from the visual effect, typical ground objects spectrum characteristics and spectrum consistency three aspects respectively. Studies show that both models can effectively eliminate atmospheric effects of ETM ＋ image, and the calibration accuracy of FLAASH model is superior to the ATCOR2 model. |
