使用定向光照增强解译线性地质构造

Enhancing Interpretation of Linear Geological Structure Based on Directional Illumination

以北京房山张坊地区为例,通过模拟各方向光照模型增强多光谱影像线性特征的方法,选择最佳光照模型以增强区域构造的线性特征,有效地提高了线性构造信息的可解译性,进行了断裂构造的遥感解译,为该区岩溶机理研究工作提供了参考。

Taking the Fangshan Zhangfang area in Beijing as an example,the paper simulated the illumination models in all direction to enhance linear characteristics of muti-spectral image, and choose the best illumination models to enhance linear characteristics of regional structure. By this method, the interpretability of the linear geological structure is effectively improved to obtain the remote sensing interpretation of the fault structure. The research provides the reference for studying the mechanism of karst.
