摘要
由于三维数字地形图中的特征点和特征线都是三维的,在其上面可以查询任意特征点的平面坐标和高程即三维坐标,使用十分方便。本文主要阐述全站仪采集三维数据的方法,重点分析了无棱镜测量方法,指出其适用范围。
As the feature points and the feature lines in three-dimensional digital map are three-dimensional,and it can search for plane coordinate and elevation of any feature point（three-dimensional coordinate）.So the use of it is very convenient.In this paper,the method of three-dimensional acquisition by total station is discussed,and the method of prismatic-free measurement as well as its application scope is analyzed.
