带空洞面对象间拓扑关系形式化描述

Formal Description of Regions with Hole's Topological Relations

利用Egenhofer等提出的含空洞的两面对象间空间拓扑关系描述框架,在四交差模型的基础上,提出了一种能描述带空洞复杂面对象间的空间拓扑关系的扩展模型——4-4ID模型,并用该模型详细推导了简单面对象和仅带一个空洞面对象间以及两个仅带一个空洞面对象间有意义的拓扑关系。

This paper used the description frame of two regions with holes which was put forward by egenhofer, based on the 4ID, put forward a new extended model 4-4ID, which can describe the regions with a hole＇s special topological relations. At the same time, this paper presented the topological relations between simple regions and regions with a hole.
