一、概述卫星像片具有广阔的视域,逼真的影像,显着的线性特征和圆形构造特征。而对于隐伏的地质构造,也能透过盖层显示信息。尤其是卫星像片具有多波段成像便于相互对比。对于区域的地貌形态、水系格局、岩性分类、构造展布一目了然。这就为在铁路选线中,应用卫星像片进行铁路综合选线提供了有利条件。本文通过京(北京)～山(山海关)改线,在滦
First, an overview Satellite images with a wide field of vision, realistic images, significant linear features and circular features. For hidden geological formations, information can also be displayed through the overburden. In particular, satellite images with multi-band imaging facilitate comparison with each other. For the region’s topography, water system, lithology classification, structural distribution at a glance. This will provide favorable conditions for the railway line selection, application of satellite imagery for railway integrated route selection.
