遥感线性构造提取方法及意义——以高燕锰矿区为例

Method and Significance of Extraction of Remote Sensing Information of Linear Feature

线性构造在遥感影像上主要表现为连续或不连续的线性体,能大致反映一个地区的基本构造格局[1]。以重庆高燕锰矿区为例,介绍了一种基于Landsat 8等多光谱遥感数据、ASTER GDEM(30m)数字高程模型数据以及Google Earth 3D影像数据并结合GIS系统进行人机交互的遥感线性构造信息提取的方法,同时结合野外地质事实分析其构造意义。

Linear feature on the remote sensing image is a continuous or discontinuous linear body which shows basic structural pattern in the studied region. The present paper deals with a method of extraction of remote sensing information of linear feature based on Landsat 8, ASTER GDEM （30 m）, GoogleEarth 3D and GIS by the example of Gaoyan Mn mine field and make an approach to significance of this method.
