摘要
利用ETM+数据目视解译矿区构造,基于ASTER数据,采用主成分分析(PCA)和波段比值结合的方法进行蚀变信息提取,并把提取结果和解译构造联系起来,分析对比,反复试验。研究结果表明:ETM+数据和ASTER数据结合的方法在提取矿化蚀变中有一定的可行性,并在内蒙古塔日根敖包地区进行蚀变信息提取实验,证明信息可靠,结果可用。
After interpret the structures in mining area by using ETM+ data,Based on the ASTER data,extracted mineralization information by using the principal component analysis(PCA) methods and the ratio of the band methods,link the experimental results and tectonic inte rpre tation,comparative and analysis and try again.The results show that:the method of extracting mine ralization information by combining ETM+ date and ASTER data has a good effect.Then make a mineralization information extraction experiment in Tarigenaobao area in Inner Mongolia.It is proved reliable,and can be widely used.
