北京市遥感矿产地质构造解译与异常提取初步分析

本文以遥感构造理论为主导,阐明全市地质构造的基本特征。通过对ETM、TM资料定向滤波、主成分分析、线性增强和假彩色合成处理后,采用目视综合解译,获得一系列遥感图件,从线、环、色、带、块及遥感异常等方面反映了遥感地质成果。

Preliminary Study on the Anomaly Extraction of Remote Sensing Interpretation about Beijing Mineral Resources and Geological Structure

According to the remote sensing structural theory, this paper systemically introduces the basic characteristics of the geological structure in Beijing City. Through directional filtering, principal component analysis, linear enhancement and false color composite for the ETM, TM data, we adopt visual integrated interpretation and obtain a series of remote sensing maps. These maps obviously reveal the remote sensing geological results according to such aspects as line, ring, color and block anomalies.
