城镇地籍EDM导线测量的精度分析

PRECISION ANALYSIS OF ELECTRONIC DISTANCE MEASUREMENT TRAVERSE IN URBAN CADASTRATION

为探讨城镇地籍电子测距导线测量的精度，分析了城镇地籍附合导线与支导线的最弱点之点位中误差的大小，对比地籍测绘规范的精度要求，提出了相关的结论和建议．

This paper analyses the value of mean square error of the weakest point of connecting traverse and unclosed traverse in urban cadastration. Comparing the accuracy demands of specification for cadastral surveying and mapping,the paper draws some conclusions and gives some useful suggestions.
