遥感以其高光谱分辨率、空间分辨率为地理研究提供了丰富的数据,这些数据各波段之间具有重要的互补性,但是也存在着大量的数据冗余.利用最佳波段组合指数法和地物光谱信息相结合的方法,按照波段组合后的信息量最大和波段之间的相关性最小的原则,对实验区的居民地信息提取选取最佳波段组合方案,最后研究表明:分别将TM4、TM5、TM波段赋予红绿蓝三种颜色,所得的假彩色图像信息丰富,居民地与周围地物在色调上具有很好的可分性,有利于信息的提取.

The remote sensing provide geographical research rich data with its high spectrum resolution and the spatial resolution.These data have very important supplementary,but also have massive data redundancy.The authors use the OIF method and consider the spectrum information of target objects.In this study,the follw factors must be consider:the information of wave bands and the difference of target objects’ spectrum information must be max,the correlation of the wave bands must be lower.In the end,this study indicate: the false color image composed of TM4,TM5,TM3 wave bands is rich in information and the residential areas can obviously differ from surrounding objects in color.So it is better for extracting the information of residential areas.
