全站仪免对中法在城区地形测量中的应用

The No-Centering Method of Total Station in the Survey of Urban Topographic

全站仪进行野外数据采集的方法目前已经相对成熟,笔者经过长期的工作实践总结出一种新的方法,这种方法不需要进行传统的对中,减少了对中所带来的误差,可应用于任何地方,特别是城市通视不太好的地区,可减少支点带来的误差。

Field data collection of total station instrument has relatively mature. There has appear a new method coming form the long-term working practice of the author ,this method needn＇t the traditional centering, so which can reduce the error of centration,which also can reduce the error caused by the fulcrum in urban areas of poor visibility conditions.
