地籍测量补测的方法及精度分析

Research on the Method of Additional Survey in Cadastral Survey and Precision Analysis

基于地籍测量中存在界址点坐标未知、界址标志丢失,在初次查图阶段需要补测,且补测部分具有面积小、分布琐碎、精度要求高等问题;分析了地籍测量中对数据的精度要求,提出独立坐标系统测量数据,运用CASS软件转换数据的测量方法,与传统的补测方法进行比较并结合实例对误差进行精度分析。得出该方法省工、省资、省时,能够达到国家技术规程的精度要求。

Based on the problems in the cadastral survey which existed unknown boundary point,lost boundary marks,required the additional survey with small area,trivial distribution and high precision in the initial stages of checking maps,this paper analysis the accuracy requirements in cadastral survey,and put forward a method of measuring dates with independent coordinate system and converting dates with CASS software,also made precision analysis of the errors with an example compared with traditional methods.The result showed the method could be able to reach the accuracy of state technological regulations and saved time and labor.
