摘要
选取Landsat7ETM+和ASTER为遥感信息提取的数据源,基于ETM+数据进行信息提取,结合ASTER数据处理结果进行对比验证,对非洲某铜矿勘查区进行遥感资源评价.通过遥感影像预处理、地质解译标志建立、影像目视解译获取区内岩性与构造解译图、遥感蚀变信息的提取、圈定找矿靶区等步骤,预测了3个成矿远景区,为后续找矿奠定了基础.
In this paper,the authors chose two data:the Landsat 7 ETM + and ASTER as the data source of remote sensing information extraction,compared their alteration information,then evaluated copper resource potential in a certain area in Africa.Through the process of the work including:pretreat the remote sensing data and select ETM + 7,4,1 combination image as base map for interpretation;extract lithologic information and the tectonic interpreted with visual interpretation;extract the chalybeate anomaly information and argillation anomaly information by ENVI;predict three copper-finding prospects,which lays a basis for the next work.
