GPS技术在地籍测量中的应用

The Application of GPS Technology in Cadastral Survey

文章针对地籍测量的要求,在介绍地籍测绘基本方法的基础上,探讨GPS应用于地籍测量的技术问题,提出切实可行的技术方案。同时,也探讨了GPS-RTK用于界址点测量的问题,提出有效的减弱或消除措施。通过实验表明,采用GPS-RTK进行界址点测量能达到地籍测量的精度要求,是可行的,特别是在天空视野开阔地区;对于困难地区,采用文章所提到的GPS-RTK与全站仪联合作业的思想能够解决界址点测量问题,满足地籍测量的精度要求。

After introducing the basic method of cadastral survey, this paper discusses the application of GPS technology in cadastral survey and puts forward practicable technical solutions according to the demand of cadastral survey. In the meantime, it discusses the application of GPS - RTK in boundary point survey, puts forward effective method of reducing or eliminating errors. Experiments prove that it is practicable and can meet the precision demand of cadastral survey applying GPS - RTK technique in boundary point surveying, especially in areas of wide vision. In difficult areas, it can solve the problem of boundary survey and meet the precision demand of cadastral survey using the solution of combined operations of GPS - RTK and Total Station.
