地块面积精度与其界址点精度关系的研究

Research on the Relationship between the Area Accuracy and Boundary Point Accuracy of a Cadastral Parcel

本文首先研究了地块面积中误差与其界址点点位中误差的关系,在界址点精度绝对均匀的情况下,导出了正多边形地块面积中误差公式。针对农村土地承包经营权调查规程(NY/T 2537(2014),分析了实测法、航测法、图解法测算面积的精度情况,为了保障2.5%的面积精度,认为界址点测量应采用实测法的精度要求,面积检测应采用重复测量的方法。本文结论对农村土地承包经营权调查实践和规程修订具有一定的参考意义。

The relationship between the area error and the boundary point error of a cadastral parcel is first researched.Under the condition that the boundary point accuracies are absolute uniformity,the error formula is derived in the regular polygon parcel of the area.According to Investigation Code Of Practice For The Right To Rural Land Contractual Management（NY/T 2537（2014）,the area accuracies with measurement method,aerial survey method and graph method are analysed.In order to ensure that the area precision is not less then 2.5%,that the boundary point measurements should be used with measurement precision,and the area test should be used with repeat measurement.This article has some referent significance to practice the investigation for the right to rural land contractual management,and to rewise the NY/T2537.
