Abstract: "This work presents a general technique to represent and identify various abstractions of spatial information in a uniform and consistent manner regardless of the dimensionality of the geometric elements used to model these abstractions. The principal motivation of this study is to provide a general spatial representation scheme that can be used by all disciplines involved throughout the lifecycle of a constructed facility to specify and reason about the facility information. However, this scheme is sufficiently general to be used in other domains in which spatial decomposition and configuration of objects are of great interest.In our implementation, the spatial information is modeled using a vertex-based, non-manifold geometric modeling system. The non-spatial attributes are handled by a separate information management system, such as a relational database, and linked to their corresponding spatial attributes in the geometric modeler."
