Abstract

GPS provides the WGS84 Geodetic Coordinate. In order to reduce the area deformation of projection, highway survey generally uses the local independent coordinate system. Taking Hainan Central Highway for example, we introduced a data processing method for HiCORS in this paper. And we constructed control net with HiCORS reference stations and third-grade GPS points, after the baseline processing and network adjustment. The accuracy of the result fully meets the requirements of highway survey specii cation.
