摘要
阐述相对点位中误差的概念及其在工程测量中的作用,介绍相对点位中误差及相对误差椭园计算方法,以示例说明点位中误差和相对点位中误差的意义和作用。
The paper expounds the conception of relative mean square error of a point and its action in engineering survey, introduces the method of computing relative mean square error of a point and relative error ellipse, and illustrates the meaning and action of mean square error of a point and relative mean square error of a point with the examples.
