测绘工程毕业论文--GPS在公路工程测量中的应用.docVIP

摘 要 数字化测图是近几年随着计算机、地面测量仪器、数字化测图软件的应用而迅速发展起来的全新内容,已广泛应用于测绘生产、水利水电工程、土地管理、城市规划、环境保护和军事工程等部门，并被广大用户所接受。而GPS做为数字化测绘的先进技术应用于公路测量则是公路外业勘测的一项重大技术革命，其应用及开发的前景十分广阔。尤其是实时动态(RTK)定位技术在公路测量中蕴含着巨大的技术潜力。本文从GPS卫星定位系统的概述入手，先介绍了GPS卫星定位技术的原理和，接着列举实例对GPS在公路测量中的应用及其对公路勘测的巨大推进作用做了详述。主要是对孝义市市区北外环公路控制网的测绘过程做了详细介绍，最后对GPS技术在公路测量中的应用前景做了展望。 关键词： GPS全球卫星定位系统； GPS控制网； RTK Abstract The digitized mapping is in recent years along with the computer, the ground survey instrument, the brand-new content which but the digitized mapping software application develops rapidly，Has widely applied in departments and so on mapping production, water conservation water and electricity project, land management, urban planning, environmental protection and military engineering, and is accepted by the user community. But GPS does for the digitized mapping vanguard technology applies in the highway surveying is a significant technological revolution which the road field operation surveys, its application and the development prospect is extremely broad. The real-time dynamic (RTK) localization technology is in particular containing the huge technical potential in the highway surveying. This article from GPS satellite positioning system outline obtaining, introduced first the GPS satellite positioning technology principle and the work regulations, then enumerated the example which surveyed to the road have made the specification to GPS in the highway surveying application and the huge advancement function.Mainly was the outer ring road control net mapping process has made the detailed introduction to the fidelity city urban district north, finally has made the forecast to the GPS technology in the highway surveying application prospect.
