Selection of Characteristic Bands in Alteration Information Extraction from Remote Sensing Images for the Heishankouyong Area,Hami,Xinjiang
摘要
Abstract
Selection of characteristic bands is a critical process for extracting mineral alteration information from remote sensing images.Taking the Heishankou area in Hami of Xinjiang as an example,we make geometric structural analysis of spectral data space and use ETM data to study the partial regression of the 7 ETM bands,and to evaluate mineral alteration information from these data.Then we select the characteristic bands for varied alteration types to extract alteration information,and use the principal component analysis method and the optimal density separation method to extract mineral alteration information.Field geological survey and spectral measurements prove that the extracted alteration information is consistent with the real situation,indicating the ideal result of this method.And this work suggests that the mineralized alteration-bearing ferruginous rock bodies on the secondary fault zone shows a good prospecting potential.关键词
