Alteration Information Extracting Of Remote Sensing Image And Prospecting Prediction In Trigonometrical Station Of S12 In The Area Of Heishanling, Xinjiang

Mineral resources are an important foundation for national economic development, sustained and steady development of industry must have an adequate reserve of mineral resources, mineral exploration is particularly important. Exploration of mineral resources at home and abroad by: geological mapping method, topography law, geological remote sensing method, such as geophysical methods. In this paper, Ruoqiang County in Xinjiang and the mountain area 1:5 million transfer project as an example to explore the remote sensing information extraction method of prospecting.The article is located in mountain areas in Xinjiang and the study measured the use of ETM + satellite remote sensing data and metal mineralization related to remote sensing information extraction method of prospecting. The course of the study, first of all, of the geological data obtained, a comprehensive analysis of remote sensing data, the establishment of its intrinsic link between. For example, studies of mineral alteration in the ion-ion or group of spectral features, as well as in the corresponding ETM images of the band (ETM1-5, 7) on the spectral characteristics of the spectral differences, which the establishment of mineralization and alteration of remote sensing information enhance the extraction model; and geometric image correction, image enhancement, cut subgraph, mosaics, such as data preprocessing, the image based on information related to enhanced extraction model. After repeated tests and statistical analysis, the paper selects the best band combination of increased synthesis of mineralization and alteration of the image information extraction. This method is used to express a specific formula, that is, "multiple data analysis + ratio + principal component analysis", in which the information used to enhance the mineralization of the "ratio of + principal component analysis", in the study selected ETM5 / 7 and the PCA (1, 4,5,7). TM741 is the best band in combination, constitute a false color images to enhance mineralization of information, the information extracted mineralization.Geological Survey through the business, combined with remote sensing image interpretation and analysis, basic research to identify areas of stratigraphy, tectonics, igneous rocks, such as the conditions of ore-forming geological background, to build a prospecting model. Black mountain in the successful extraction of information based on the mineralization, using the method of the mountain areas and remote sensing exploration forecasts, the forecast made two areas is forecast to more abundant resources.
