In contrast with traditional theodolite station surveying in which it stand at known points, for arbitrary operation, the station stands at unknown points used to survey known points.The paper introduces the surveying operation for arbitrary theodolite station based on LEICAlc305.%全站仪传统的作业模式是在已知控制点上安置仪器,然后进行测站设置,自由设站法是在未知点上安置仪器,观测已知点来求得未知点的坐标。文章介绍了基于LeicaTC305全站仪自由设站的具体施测方法及其应用。
