Study on theTechnology of Extracting Alteration Information for Remote SensingImagery with ERDAS8.7

本文探讨了在山东省招远市使用Landsat-ETM+影像进行蚀变带(铁氧化物、羟基和碳酸盐)识别的方法，并提出了一种改进的遥感蚀变信息提取方法，该方法基于宁夏中卫地区铀矿化关键因素分析，通过屏蔽非目标铀矿化地层范围，减少了噪声对蚀变提取的影响。

Study on the Remote Sensing Imagery Alteration Information Extracting Technology: Case Study of Gold mineralization in Zhaoyuan City, Shandong Province, China

Excerpt Alteration extraction of Landsat-ETM+ imageries has been used for many years to explore gold minerals in Zhaoyuan city in Shandong Province. This paper aims to introduce some methods to detect the alteration zones (iron oxides, hydroxyl, and carbonates) in the wall rocks using Landsat-ETM+ imagery. Band selection played an important role in this research. Before choosing the bands, the basic information, the correlation coefficient of all bands, and the correlation between the bands and alteration zones were analyzed. By using the spectral characteristics of the wall rocks and different band ratios (reflected∕absorbed), the alteration zones in the wall rocks could be delineated. Owing to the presence of gossans in Zhaoyuan city, the mixture of iron oxide and clay minerals affects the spectral reflectance of the satellite data. Comparing the research result with existing mines, the technology identified 43 (89.5%) out of the total 48 mines.

A Study on the Extracting Method for Remote Sensing Alteration Information with Essential Mineralization Factors

Based on the analysis of uranium mineralization essential factors in Zhongwei area of Ningxia,this paper put forward an improved method of alteration extraction from ETM data with mineralization essential factors.The noise impact on alteration extraction was reduced by masking the range of non target strata of uranium mineralization.It's proved through field verification that the method can improve the alteration extracting accuracy,and several anomaly uranium were found in Zhongwei area with the clue of alteration mineral extracted by improved remote sensing method.
