摘要
针对只有一个热红外通道的遥感数据,利用归一化植被指数与地表比辐射率具有较高的线性相关性进行地表比辐射率的遥感反演,介绍了基于归一化植被指数定量反演地表比辐射率的4种方法,以湖北省荆门市地区的Landsat5 TM数据为研究对象,精度0.01的MODIS LSE产品为标准数据,对比分析了4种基于NDVI的地表比辐射率反演方法,分别从像元尺度和分类尺度总结了4种地表比辐射率反演方法的普适性和精度。
In this paper, foue methods to retrieve the land surface emissivity（LSE） based on the high linear relation- ship between the Normalized Differential Vegetation Index （NDVI） and LSE are introduced. Taking the Jingmen city of Hubei province as an example, the quantitative retrieval of LSE was realized by the four methods in the scope of Landsat5 TM data, respectively analyzing the applicability and the accuracy from the pixel scale and classificaion scale by compa- ring the results of LSE and 0.01 MODIS LSE product.
