平面控制网闭合环的自动寻找

Automatic Searching for Closed Loop in Plane Control Network

闭合环的自动搜索一般应用于水准网以及GPS网,而对于常规的平面控制网多数采用给出环线信息的方法计算闭合差,程序执行时需要输入大量的信息,增加了工作量,使用起来不方便,本文通过对平面观测数据的整理,可以获得与水准网或GPS网相同的环线信息,进而将闭合环的自动搜索应用于极条件、导线闭合或附合条件、组合角条件的自动搜索。

The automatic searching for closed loop is commonly used in leveling notwork or GPS network adjustment computation. Actually, given loop information is used to calculate the closed error loop for a traditional plane control network, as so much quantity of information has to be input before the executing of the software heavy workload and inconvenience will be caused. By cleaning up the plane observation data, loop information can be obtained the same as the leveling network and the GPS network. Furthermore, the automatic searching for closed loop can be used in different circumstances such as the limited condition, the closed or connecting traverse condition and the combination angle condition.
