三维地理信息系统中几何特征的误差模型

Error Models for Geometric Features in Three Dimensional GIS

  • 摘要: 本文提出了三维地理信息系统中几何特征的误差模型。基于面表示的三维GIS的特征被分为点、线段及线,该模型给出这些特征的一种误差描述,即围绕着这些几何特征的量测值的一个范围。

     

    Abstract: This paper presents the error models developed for handling geometric features in three-dimensional Geographical Information Systems.These features include points,line segments and linear features.The developed approach provides a confidence volume model for each feature type.
