【摘要】 本文对陆地卫星专题制图仪（ＴＭ）数据进行直方图分析、相关分析及主要成分分析，结果表明，ＴＭ５提供的信息量最大，ＴＭ５与ＴＭ７，ＴＭ１、ＴＭ２与ＴＭ３之间存在着显著相关，信息重复量大，ＴＭ４、ＴＭ６则独立性强，在选择波段及波段组合中应给予重视。直方日均恒化增强处理可提高图像的分辨率。ＴＭ数据与数字高程数据复合，实现ＴＭ图像的立体显示，充分体现了地理信息系统的应用前景。更多还原

【Abstract】 Histogram analysis. correlation analysis and primary analysis were used to process data of seven TM bands of Landsat images in Taishan Mountain region. The results showthat TM5 can provide much more information than others. There are very significant correlation between TM5 and TM7, and among TM 1, TM2 and TM3. The information independence of TM4 and TM6 is evident. The TM images were enhanced through histogramequalization. The three dimensional images of Taishan Mountain were obtained by covering digital elevation mode data with TM data on geographic information systenl (GIS).更多还原
