摘要
RTK是能够在野外实时得到厘米级定位精度的测量方法,它采用了载波相位动态实时差分方法,它的出现在工程放样、地形测图,各种控制测量等测量工作中,极大地提高了外业作业效率。根据笔者多年测量经验,地形测图方面采用的方法:运用实时动态(RTK)测量技术,结合南方数码公司"工程之星3.0"软件,采用清华三维编码、简码方式采集野外数据,用VB小程序进行数据格式转换,在"南方CASS7.0成图系统"软件,展现数字化地形图。
RTK is able to in the field of real-time cm level positioning precision measurement method, which uses the carrier phase dynamic real time difference method, is the GPS application major milepost, it is project lofting, topo- graphic mapping ,various control measurement brings new dawn, greatly improves the work efficiency and industry. Ac- cording to the writer＇s many years experience of measurement, topographic mapping the method in use：the use of real- time dynamic （RTK） measurement technology, combined with the digital company ＂Project Star 3.0＂ software, adopt three-dimensional coding, code the collection of field data, using vb small program for data format conversion, in the ＂ Southern CASS7.0 mapping system＂ software display,digital topographic map.
