中文摘要：

为定量比较TM和LISS 3数据的反射率反演结果差异,以北京市2005年5月6日的TM数据和2005年5月2日的LISS 3数据为信息源分别进行了地表反射率反演,首先对图像进行了基于图像特征的大气校正,然后对地表反射率进行了反演,并对反演结果进行了比较.结果表明各波段的rmsd值分别为0.030、0.071、0.072和0.078.各个类别的rmsd值分别为0.008、0.087、0.066、0.079和0.056.

英文摘要：

In order to compare the reflectance retrieval results obtained from Landsat TM and IRS LISS 3 data respectively, Landsat TM and IRS LISS 3 images of Beijing city acquired on May 6th and May 2nd, 2005 separately were used in this study. Firstly imagebased atmospheric correction was carried out, followed by land surface reflectance computation of Beijing city and a comparison between the two retrieval results was then presented. The results show that the Root Mean Square Deviation （RMSD） for each band is 0. 030, 0. 071,0. 072 and 0. 078 , for each class is 0. 008,0. 087,0. 066 ,0. 079 and 0. 056 respectively.
