摘要
本文先从理论分析入手,讨论了测边三维网和只观测水平方向与垂直角的三维网的使用条件,然后用实例进行验证与修正,并在此基础上,对这两种网的使用条件提出了具体建议。
The application conditions of 3-D trilaterational network and the 3-D network in which horizontal directions and vertical angles are only observed will be firstly discussed from theory, and then analyzed and examined by real case. Some suggestions for using these two networks are also given.
