摘　　要：在城镇图根控制网布设中有时镇区范围较大,在清华山维平差软件中,有边长输入不能重复输入,角度不能遗漏等缺点,内业角度和边长数据输入较麻烦,往往容易出错,以某城镇地籍图根控制网为例,在全镇图根控制网布设中将其布设成整体控制网和将全镇分成几部分分别布网,布设成几个局部控制网,对整体控制网和局部控制网分别进行平差计算,通过在整体控制网和局部控制网中设置共用边,分别计算共用边上的待定点,通过坐标比较,分析大的测区范围控制网布设成局部控制网的可行性。In towns figure root control network is sometimes township range is larger,in NASEW soft- ware adjustment,input can＇t repeat input side length, Angle can＇t miss such as faults, more trouble Angle and length of data input in the industry, often prone to errors, this paper takes a certain town cadastral map the root control network as an example, in the whole town in figure root control network will be designed into overall control network and the whole town is divided into several parts and net respectively, setting into several local control net, to control the whole network and local control net- work adjustment calculation respectively ,through the overall control and local control net set in the Shared edge, Shared stay at the edge of fixed-point, are calculated respectively through comparing co- ordinates, the analysis of large measurement range of the feasibility of the control network into a local control network.
