摘　　要：为解决常见地图平面数学基础应用错误问题,本文提出了一种地图平面数学基础检查鉴定的方法。在优势标志点残差统计的基础上,设置异常残差阈值,对非优势标志点进行残差分析,结合非优势标志点的类型和分布特征进行数学基础应用分析。实验表明,本方法在检查和鉴定坐标系误用、地图投影错误、比例尺设置错误、椭球及投影参数设置错误等方面具有一定的可靠性。该方法可作为制图工作自检、互检、专项检查及地图审校阶段的一般方法。In order to solve the problem of common errors in the application of the horizontal mathematical basis of maps,this paper proposes a method for inspecting and verifying the horizontal mathematical basis of maps.On the basis of residual statistics of dominant marker points,the threshold value of abnormal residuals is set,residual analysis is conducted on non-dominant marker points,and mathematical basis application analysis is conducted in combination with the types and distribution characteristics of non-dominant marker points.Experiments show that this method is reliable for inspecting and verifying the errors of coordinate system misuse,map projection,map scale setting,ellipsoid and projection parameter setting.This method can be used as a general method in the stages of self inspection,mutual inspection,special inspection and map review.
