摘要
利用差分算子和时间序列分析工具导出了地图曲线数字化误差估计公式。通过计算分析说明了根据曲线数字化数据估计数字化误差的具体方法。
The mathematical formulas for the estimation of dinitizing errors along curves in a cartographic map have been derived by means of the difference operator and time-sequential analysis. Numerical examples presented in the paper show how to use the formulas to estimate the digitizing errores after having a set of digitizing data for curves.
