研究如何修复由于扫描行校正器SLC故障而造成的数据坏行,成为国际遥感研究的热点。文章在总结现有的修复方法基础上提出用相同时相的MODIS09数据修复SLC-off数据的方法。该方法采用时空自适应反射率融合模型(STARFM)算法实现MODIS09数据和TM/ETM+数据的融合,获得与SLC-off数据相同时相和空间分辨率的融合数据,然后采用局部线性直方图匹配完成对SLC-off数据填充。实验证明该方法修复效果明显好于传统方法,解决了传统修复方法中存在的一些问题,一定程度上提高了ETM+SLC-off数据的利用率。 更多还原

【Abstract】 Study on how to restore SLC-off data has became a hot topic in the international remote sensing domain.At the basis of summarization of present restoration methods,a new method to restore the SLC-off data using the same time MODIS09 data is proposed.The steps are as follow:Firstly,using the algorithm of a spatial and temporal adaptive reflectance fusion model(STARFM)to fuse the MODIS09 and TM/ETM data.After data fusion,we can obtain the fusion data with the same spatial and temporal resolution o... 更多还原
