大比例尺数字化地形图测绘方法的探讨

On exploration of surveying methods of digital topographic maps with large scale

对大比例尺数字化地形图测绘方法进行了介绍,分别具体阐述了全站仪测图、GPS-RTK技术、三维激光扫描技术三种数字化地形图测绘方法,并对各种方法的特点和适用范围及作业原理进行了总结,以指导实践。

The paper introduces the surveying methods of digital topographic maps with large scale,illustrates the total station device,GPS-RTK technique and 3D laser scan technique,and sums up the characteristics,application scopes and principles for the three methods,so as to direct the practice.
