摘要
依据工作区ETM+数据特征,采用主成分分析、比值处理、平滑滤波等技术进行遥感蚀变信息提取、获得遥感蚀变信息异常图。深入研究蚀变信息异常的分布特征,结合区域成矿特点,表明蚀变异常信息是重要的找矿标志。
According to the characteristics of ETM ＋ data in this area, we apply the analysis of characteristic main composition, ratio processing and smooth filter, etc, to Abstract ing the remote - sensing alteration informa- tion and achieving the map of remote - sensing alteration information anomaly. According to the analysis of distribu- tion characteristics of alteration information anomaly, in combination with the regional characteristics of metallogen- esis, we think the alteration anomaly information is the important prospecting criteria.
