| 摘 要： | 方向关系是空间关系研究的重要领域,应用十分广泛。因此,空间数据库中对方向关系的研究越来越引起人们的注意。本文在分析和研究了文6]提出的方向关系模型的基础上,对该模型做了进一步扩展,提出了一种用关系矩阵表示方向关系的新方法,并对原子方向关系的合成进行了深入研究,提出了不同于传统理论中使用原子方向关系合成表来求解的新的基于矩阵运算的原子方向关系的合成方法。

| Abstract: | The direction relation is an important researching area in spatial relation so it has received more and more attentions than ever. This paper we have extended the model further and offered that direction relations are ex- plained by direction relation matrix. Moreover we have thorough researched the composing of atomic cardinal direc- tion relations and presented methods of composing of atomic cardinal direction relations which differs from traditional methods which using composition tables for direction relations. |
