对地观测技术在铁路勘测设计中的应用

研究目的:长期以来,虽然对地观测技术在我国铁路勘测设计中发挥了重要的作用,但是,当新的对地观测技术取得了突飞猛进发展的时候,其在我国铁路勘测设计中的应用却出现相对滞后,目前,中国铁路已经步入高速时代,针对最新的对地观测技术发展,铁路工程技术人员必须找到适合我国铁路勘测设计新的工艺流程和技术突破点。研究结论:针对目前最新对地观测技术发展态势,铁路勘测设计人员一方面要继续挖掘既有对地观测技术和资料的应用潜力,也要对数码航空摄影、机载激光雷达、高分辨率卫星影像数据等最新的对地观测技术和成果加大研究、应用力度。对地观测技术既可应用于国家基础测绘,也可广泛应用于铁路地形图测绘、铁路线路选线设计、铁道工程地质勘测、铁路环境评价等领域。

Application of Earth Observation Technology in Railway Survey and Design

Research purposes: For along time,although the earth observation technology plays an important role in railway survey and design,but there is relative lag of its application in railway survey and design in China when the new earth observation technology achieves a rapid development.Now the China railway has entered the era of high speed,with the development of the latest earth observation technology,the new process flow and the breakthrough of the earth observation technology that is available for the railway survey and design mus be found. Research conclusions:Aiming at the development trend of the latest earth observation technology development,on one hand,the applied potential of the existing earth observation technology and data should be unearthed,and on the other hand,the research and application should be strengthened for the latest earth observation technology and its achievements,such as the digital aerial photography,the airborne laser radar and the high resolution satellite image data.Not only can the earth observation technology be applied in the national basis mapping,but also can be applied in the railway topographic mapping,railway track alignment,railway engineering geologic survey and railway environment evaluation.
