TM图象对应分析研究

Study of Correspondence Analysis on Landsat TM

利用对应分析法对内蒙色尔腾山地区的ＴＭ图象进行了分析，达到了图象分类和增强特征信息的目的。

Landsat TM image is one of the primary sources of remote sensing geological information at present. It provides a lot of information for mapping and recognizing unaltered and altered rocks and vegetation and other things in the region of visible and near infrared and short-wave infrared and thermal infrared bands. Because its thermal infrared band(TM7) has a low spatial resolution, generally, it isn't used. This paper uses Correspondence Analysis (CA) to process the TM image at the Seerteng Mountain, Inner Mongolia Autonomous Region, and acquired good results and shows the useful information that CA provides.
