基于ETM数据的庞西垌地区断裂信息提取

Fault information extraction based on ETM data in Pangxidong area

针对庞西垌地区植被高覆盖特征,主要选用ETM+数据,结合DEM数据,采用正向主成分分析、波段比值、多波段信息合成等处理方法,提取与成矿控矿相关的线状、环状构造信息,结合该区相关地质资料,实现研究区构造综合解译。

According to the characteristics of high vegetation coverage in Pangxidong area, the authors selected ETM ＋ remote sensing data and DEM data for processing. The linear and ring ore-controlling structure information was extracted by the methods such as forward principal component analysis, band ratio and muhiband information synthesis. In combination with geological material, the authors interpreted and recognized the structural information in the study area.
