| 摘 要： | 以快速、准确地对Landsat卫星的系列影像几何精校正为研究内容，以长江口附近为研究区域，先用地形图对高空间分辨率影像几何精校正，后用该影像对低分辨率影像进行校正。研究结果表明：用校正好的高空间分辨率影像ETM＋-Pan对低空间分辨率影像进行校正，具有较好的效果；而相同空间分辨率的影像（如ETM＋-MULTI和TM）之间一般不适宜相互进行校正。

| Abstract: | The research focuses on rapidly and accurately geometric correction of Landsat satellite images.The research field is around the estuary of the Yangtze River.Relief maps are used as standard space to practice geometric precision correction of high space resolution images,and then these images are used for correcting low resolution images.The conclusion indicates that it works better to use high space resolution ETM+-Pan images corrected as standard space to correct low space resolution images.But the geometric correction between two images with the same space resolution(such as ETM+-MULTI and TM) doesn't show good result. |
