摘　　要：通过卫星遥感技术进行地质填图以及找矿越来越成为一种快捷有效的手段。遥感地质解译根据遥感影像,通过遥感图像的数字处理,来提取与岩性特征和构造特征相关的地质信息,再结合工作区的地质资料进行地质填图。ETM+具有从可见光到热红外的波谱范围,能满足一定矿物、岩石的岩性特征的划分需要。对ETM+的多波段数据采用主成分分析法和多波段组合分析方法。Through satellite remote sensing technology for geological mapping and prospecting has in- creasingly become a quick and effective means. Geological interpretation of remote sensing images based on remote sensing, through remote sensing image processing, to extract the structural features and litho logic features and geological information related to, the work area combined with geological mapping of geolog- ical data. ETM ＋ has from visible to thermal infrared spectral range, to meet certain minerals, rock litho logy division needs. Of the ETM ＋ multi--band data using principal component analysis and multi--band combination method.
