线要素化简算法几何精度评估

Geometric Accuracy Assessment of Linear Features' Simplification Algorithms

  • 摘要: 在分析化简算法对线要素精度影响主要分为几何精度和属性精度两方面的基础上,针对算法化简过程中曲线在几何特征和点的位置发生变化的特点,对线化简算法的几何精度实施评估,并提出了线的曲折度、位置误差等几何精度评估指标,选择了几种典型的化简算法进行了评估实验,得出了较客观的结论。

     

    Abstract: On the basis of analyzing the influence that linear features' accuracy by simplification algorithms can be divided into geometric accuracy and attribute accuracy,aiming at curves' characteristics on geometric character and position of points change in the process of simplification,considering all the change of linear features' accuracy,position accuracy is the most important and quantitative easily,a series of evaluating figures of geometric accuracy are proposed.Several typical simplification algorithms are evaluated and some credible conclusions are given.
