摘要
方向关系的定性推理是GIS中的一个重要的理论问题。本文介绍基于井字空间的方向关系定性表示,着重讨论基于方向关系组合运算表的定性推理,最后给出一个基于方向关系组合运算表的定性推理算法。
Qualitative reasoning of directional relation is one of the key theoretical issues in GIS. This paper focuses on the qualitative reasoning based on composition operation table of directional relation. First, the qualitative representation of directional relation based on space with neutral zone is introduced. Then, the qualitative reasoning based on composition operation table of directional relation is mainly discussed. Finally, a qualitative reasoning algorithm based on composition operation table of directional relation is also given.
