基于连续的观点和等概率密度误差模型,研究矢量GIS平面随机线元误差模型的几何特征,探讨几何特征的确定思路与方法,为矢量GIS空间线状实体误差分布特征及其最高精度点位置的确定奠定理论基础。通过实例计算与可视化分析,验证理论推导的正确性,得出若干重要结论。

Provides a disquisition on geometric characteristic for error model of 2D random linear segment in vector GIS,discusses ascertaining theory and methology based on continuous viewpoint and the equivalent probability density error model(marked as Tepdem) as well,and which establishes a theoretical basis for both error distribution characteristic of spatial linear entity in vector GIS and ascertainment method for point position with highest coordinates accuracy.Test validates the correctness on theoretical ded...
