Abstract
The digitized mapping is in recent years along with puter, 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 munity. 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 was the outer ring road 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.
