Abstract:
The spatial alignment of digital resources is necessary for each process in the life cycle of an asset in the built environment. However, there is currently no way to explicitly describe the spatial relationships inherent in the resources in a machine-readable and vendor-neutral way. Therefore, the paper presents a schema to superimpose heterogeneous data in a digital space. The schema defines four main classes inherent in the Architecture, Engineering and Construction (AEC) industry: Global, Asset, Document and Entity Space. Global Space represents the Asset's physical location, while the Asset Space is the digital replica of the built object superimposing all related resources of the building. Each resource defines its own Document Space, which in itself contains one to many Entity Spaces. An Entity Space is a coherent unit of information, such as a section or a model. Moreover, the schema provides a means to express the relationships between the different space types. To verify the approach, we demonstrate the application with an example bridge data set. This work should serve as a preliminary step towards automating the spatial linking of heterogeneous resources in the built environment.
