Road Survey
Road surveyor The survey work runs through the whole road construction. However, the current GPS technology has to erect base stations while the precision decrease with distance increasing between the rover stations and base stations. Therefore, the study and application on the CORS technology is appeared. This paper describes the composition and principle of CORS system, and analyzes the application of CORS in the road control surveying, road center lines laying-out, and vertical and transverse section. Finally it summarizes some problems of the CORS system development, and looks forward to the CORS system development.
Highway surveying is a specialized type of land surveying generally conducted for government agencies during the planning stages of a highway development project. During the construction process, a highway construction survey can ensure that progress is occurring as it should, and that the highway is located precisely where it should be. After the highway is built, a highway survey can be used to provide an accurate layout of roadways, utilities, storm drainage systems, overhead wires, nearby buildings, and other features of the landscape.
