拓扑关系的描述和区分是建立在空间目标相互作用过程中目标集合及其分量集合拓扑特性变化基础之上的。对于两个简单面域间的空间拓扑关系描述研究已经很多,而对于带空洞的复杂面域间的空间拓扑关系的描述却相对较少。本文利用Egenhofer等提出的描述带空洞的面域间空间拓扑关系描述框架,在四交差模型的基础上,提出一种能描述带空洞的复杂面域间拓扑关系的扩展模型——D4ID模型,并用该模型推导了一个简单面域和一个带空洞的复杂面域间有意义的23种拓扑关系。
Description and differentiation of topological relations is based the changes of topological properties of spatial objects sets and its components before and after their intersection. There were many researches about two simple regions special topological relations, but the researches about the regions with a hole' s topological relations are relatively fewer. This paper used the description frame of two regions with holes which was put forward by Egenhofer etc. based on the 4ID, put forward a new extended model - D-4ID (Double-4ID) which can describe the regions with a hole' s special topological relations. At the same time, this paper deduced 23 kinds of topological relations between a simple region and a region with a hole
