摘要
采用方差分析法估计地图数字化坐标数据的综合方差 ,研究了不确定度估计中置信系数k的确定 ,给出了计算方法 。
A variance analysis method is used to estimate the synthesis variance of coordinate data in map digitization. The determination of confidence coefficient k in the estimation of uncertainty is studied. And its calculation method is given. Finally, an example of map digitization shows the way to use this method.
