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。
because of the three-dimensional digital topographic map feature point and characteristic line is three-dimensional, in its above can be inquires the arbitrary feature points plane coordinate system and elevation that three-dimensional coordinates, use very convenient. This paper mainly expounds the electronic tachometer acquisition of 3d data method, measurement method is analyzed, and points out that the prism range.
