GIS中曲线误差带模型的一种算法

An Algorithm for Error-band Determination of Curves in GIS

  • 摘要: 针对GIS中对曲线位置不确定性分析的要求,提出了一种采用数值方法计算拟合曲线点位误差的算法,给出了确定GIS中任意曲线误差带模型的具体计算步骤与计算公式,并结合实例,绘制了三次样条拟合曲线的误差带。

     

    Abstract: A practical numerical algorithm for calculating the errors of any point on a curve in GIS is introduced. The main approaches of error-band determination of arbitrary curves are given. As an example, the error-band model of a cubic spline is calculated.
