基于地表覆盖的TM影像波段选择定量分析算法应用研究

摘要

Land cover change information extraction more dependent on the rich,accurate and reliable for a long time relative to multi -level multi-resolution multi-source data,in order to obtain the land cover information,must be the image-band to optimize the combination.Different band combinations the effect of different map display,multi-spectral image synthesis requires the band combinatorial optimization,the paper focuses on land cover band of TM,which are frequently used in the research and application of multi -spectral data,land applied research to be learned.%地表覆盖变化信息提取更加依赖丰富、准确、可靠的多时相、多层次、多分辨率、多源的数据,因此,为了获取地表覆盖的信息,必须要对影像波段进行优化组合.不同的波段组合对不同的地图显示的效果不同,多光谱影像合成需要进行波段组合优化,本文重点针对地表覆盖研究中经常采用的TM的多光谱数据的波段选择问题,对地表覆盖研究具有借鉴意义.
