摘　　要：文章介绍了上海某石化厂厂区间石化管线三维坐标测量首级控制网(GPS平面控制网、精密水准高程控制 网)的建立及数据处理方法,对比分析与讨论了对基点进行严格筛选的必要性,为保证GPS网的精度对基 准点进行了检核,并对三维控制网的稳定度进行了评定。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.
