基于FLAASH模型的MODIS1B数据的大气校正

Atmospheric Correction on MODIS1B Satellite Image Based on FLAASH Model

主要介绍了FLAASH大气校正模型的主要原理及算法,并运用ENVI软件中的FLAASH大气校正模型对上海长江口地区MODIS1B卫星影像进行大气校正,对校正前后的影像进行对比分析。研究表明,MODIS1B卫星影像经过FLAASH大气校正后,较好地消除了大气影响。

The main principles and algorithms of FLAASH atmospheric correction model were mainly introduced.FLAASH model was used to make the atmospheric correction on MODIS1B satellite images in Shanghai Yangtze estuary area.And the comparative analysis was made on the images before and after correction.The research showed that the atmospheric influences of MODIS1B satellite images could be eliminated well after FLAASH atmospheric correction.
