Rock Spectrum Analysis Of Features And Inversion Applied Research

The thesis with "the mineral resources remote sensing geological survey of the west kunlun metallogenic belt" project, carried out a inversion application research which based on a WorldView-2 and ASTER multispectral data of lithological, then take the thorough analysis WorldView-2 and ASTER data characteristics, on the basis of analysis, carried out the measured rock spectral classification, data preprocessing and spectrum inversion technology test research methods. Ultimately, preliminary exploration set for the end of the collaborative data extraction+spectral matching lithology identification method. And this method is applied to West Kunlun Ke Liyang region, better matching.The results show that this method can be used to the geological survey of the adjacent area. The study of remote sensing geological interpretation in determining lithology has some auxiliary function. The thesis research achievements are as follows:(1) In this thesis, the remote sensing image data and the measured spectral data pretreatment method:image texture information of remote sensing data interpretation and spectral information to identify two different purposes, WorldView-2 and ASTER two of multispectral datatest and summed up the best pretreatment method; the measured spectral data with a jump point removal, smoothing, resampling approach, the final paper has laid a good data base.(2) papers on the basis of analysis of the spectral characteristics of typical minerals and rocks and affect the spectral factors, using SPSS statistical software have been classified in the measured spectrum, and one of two categories are analyzed in detail and draw characteristics and mineral composition of the spectral curve and closely related to the content of the conclusions for the late lithology identification has played a good role in paving the way; WorldView-2 and ASTER two multi-spectral data of their own advantages, do not overlap the band superimposed together, the new spectral curve, applied to the follow-up study of the lithology identification.(3) On the basis of the method, initially explored a set of the lithology identification methods for collaborative data. The main contents include the end of the extraction and spectral feature matching, and match results match the trend of a variation of the auxiliary method.(4) the research applied to West Kunlun Ke Liyang regions, achieved good application effect of lithology identification. Description This method is in use in the conditions adjacent areas, eliminating the need for a certain amount of work for the field survey.
