alteration information extraction

The characteristic spectrum produced by the interaction between the electromagnetic wave and surface rock is the theory basis of the mineralizing alteration information extraction by remote sensing.

电磁波与地表岩石、地质体发生作用，产生其特征光谱为遥感提取矿化蚀变信息提供了物理基础。

It provides the scientific basis for the experimental research of image processing techniques for extraction of the TM RS information, related to the Cu-mineralization and alteration.

以此为依据，进行了提取与铜矿化蚀变相关的TM遥感信息的计算机图像处理技术方法研究。

Geological Remote Sensing information extraction mainly includes the extraction of alteration anomalies, of the linear formations and of the lithology information.

遥感地质信息提取主要包括遥感蚀变信息的提取、线性构造信息的提取和岩性信息的提取等几个方面。
