摘要
主要研究了二维空间中空间对象间关系的定性表示。介绍了基于RCC的拓扑关系定性表示,讨论了方向关系的定性表示,给出了一个将拓扑关系定性表示和方向关系定性表示相结合的定性表示模型——SR表示模型。
Spatial relation is one of the key theoretical issues in GIS. This paper focuses on the qualitative representation of spatial relations to 2D spatial objects. First, the qualitative representation of topological relations based on RCC is introduced. Then, the qualitative representation of directional relations is discussed. Finally, a qualitative representation model, SR representation model, which combines qualitative representation of topological relations and directional relations, is given.
