摘要
阐述了由边境地区已有控制点覆盖不均匀性引起控制网型单侧布设方式的精度评定,采用单侧GPS控制布网、网连接方式,解决边境地区控制网布设,通过控制网布设的有效控制和精度评定,确定在中越边境地区大范围跨级GPS控制网的精度满足E级GPS控制网精度指标,在边境地籍地形测量控制中得到良好应用。
The paper illustrates the accuracy evaluation of the unilateral allocation of controlling network types caused by the uneven coverage of existing control points at bordering areas,adopts the unilateral GPS controlling network allocation,the network connecting ways to solve the allocation of the controlling networks at bordering areas,identifies the accuracy of the large-scale skip-level GPS controlling network at Sino-Vietnam borders meets the accuracy index of the E-level GPS controlling network by undertaking the effective control and accuracy evaluation over the allocation of controlling network,so it has better application effect in the surveying control of the cadastral terrains of borders.
