Title:

Topological operators in a 3D Spatial Query Language for Building Information Models

Author(s):
Borrmann, A.; Rank, E.
Abstract:
The paper describes the definition and implementation of topological operators which form part of a 3D Spatial Query Language that has been developed to query Building Information Models using spatial conditions. The partial models resulting from spatial queries can be used as input for numerical simulations and as exclusively modifiable subsets in the context of collaborative planning activities, for example. Because human language is vague and ambiguous, the semantics of the provided 3D topolo...     »
