GPS RTK技术在城镇地籍二调中的应用

Application of GPS RTK technology in city cadastre for the second national land surveying

针对GPS RTK精度能否满足二调城镇地籍控制测量要求的问题,本文结合某镇二调地籍控制测量项目,利用以GPS RTK技术为主、全站仪技术为辅的方法来加密图根控制点,通过对RTK测量成果的内符合与外符合精度分析,实践证明GPS RTK技术应用于二调地籍图根控制测量可行。

In order to answer the question whether the precision of GPS RTK can meet the requirement of city cadastre control surveying for the second national land survey, this paper gives a case project of a city cadastral control surveying to prove that. The project adopts the method of GPS RTK technology-based, supplemented by Total Station technology to encrypt the root control points. According to the analyses of the GPS RTK survey results from two aspects, i.e. inner precision and external precision, it demonstrates that GPS RTK technology can be applied to city cadastre control survey for the second national land survey.
