双树乡1∶1000地形图测量技术设计

1∶1 000 Topographic Survey Technology Design of Shuangshu Rural Area

设计利用全站仪与GPS-RTK联合作业进行野外数据采集,通过CASS6.0成图软件进行内业成图,完成龙港区双树乡1∶1 000地形图测量工作。主要叙述了RTK技术在地形图图根测量、碎部测量中的可行性和RTK外业测量的操作步骤、注意事项,阐述了RTK定位技术的相关原理,说明了RTK与全站仪联合进行数字化测图是一种高速度、高效率的新方法,对于地形条件复杂的地区,考虑到全站仪与RTK技术的优缺点,可以采用RTK与全站仪联合作业的方式进行地形图的测绘。在测区内不需要进行图根控制测量,使RTK与全站仪优势互补,可大幅度提高测量速度,且可保证测图精度。

The design collected fieldwork data using the total station combined with GPS-RTK.By the mapping software CASS 6.0,it completed office work of the 1∶1 000 topographic surveys in Shuangshu Rural area,Longgang district.It mainly described the feasibility of the RTK technology in the topographic survey and the detail survey,and it also described the steps of the RTK wild field survey and the issues which should be paid attention to.It also indicated the relative theories of the RTK positioning technology.It introduced that using the RTK technology combined with Total Station to make a digital mapping is a high-speed,high efficiency,the new method.For the region with a complex terrain,taking an account of the advantages and disadvantages of the total station and RTK technology,we can conduct topographic survey using the total station combined with RTK.In measured area it does not need to carry on the mapping control survey,we can make up the advantages of the RTK and the total station to each other.Thus it can raise the survey speed in a large scale,and may guarantee the mapping precision.
