It was confirmed by sampling in site and on image, that there are anomalistic characteristics of spectra (high reflection in NIR TM51.55μm-1.75μm) in the Lancangjiang Lanping Region. It provides the scientific basis for the experimental research of image processing techniques for extraction of the TM RSinformation, related to the Cu-mineralization and alteration. The best results were get by the principle component analysis. The geologic nature of the anomalies was evaluated by comparison with the geological work in Hong to jian area and by the theoretical calculation of the image sampling. Becuse of the fact,that the image preprocessing (the geometric restoration, the brightness scaling, the multivariate statistics, the optimized choice of TMchannels etc.) was accomplished for the whole region uniformly. So it is reasonable to consider, that the obtained processing technique is also applicable for the whole region. And this paper describes it with full and accurate table(4), formulse(2), graphics(4) and colour images(5).
