| Abstract: | This paper introduces the establishment of 3 - D control network (GPS plane - control network and leveling - control network) in one case of petrochemical pipes surveying. The data processing method of GPS network is demonstrated in detail. The necessary of selection and validation of bench points in this network is discussed and the stability of the whole control networks is also evaluated. |
