摘要 根据围岩蚀变在多波段遥感图像(TM)上具有的光谱特征,利用比值分析、主成分分析及比值增强后主成分分析等方法,对
四川省稻城地区围岩蚀变信息进行提取和分析,通过多层次的筛选和评估提取矿区异常区,制作遥感异常图。

Abstract: Abundant spectral and continuous spatial information of the satellite TM data is being applied
extensively. On the basis of analyzing spectral characteristics of TM image data and according to spectral
characteristics of rocks and ores as well as the theory of extracting information from remote sensing data,this
paper utilized such methods as band ratio, principal component analysis and principal component analysis after
ratio strengthening to extract mineralization-alteration information. Through sieving and evaluation, the
prospecting target can be delineated and the remote sensing map can be drawn. |
