Unfortunately , 也ey have so far only been defined for and applicable to sirnple objects like single points , continuous lines and simple arεas. not involving the design , definition , and description of topological relations operating on the complex objects. This article tríes to make an effort to this gap and pays attention to the spatial areas with hol臼. Based upon the idea of space partition and object decomposition , topological components of an area ob- ject with holes are defined by the use of the concept of neighborhood in the point set topology , which is a natu- ral extension of the definitions for topological co
