SYSTEMS ARCHITECTURE FOR MANAGEMENT OF BIM, 3D GIS AND SENSORS DATA
This paper presents a system architecture for structuring and manipulation of Building Information Models (BIM), three-dimensional (3D) geospatial information, point clouds and time series data obtained from sensors. The system consists of four layers including data pre-processing, data structuring and storage, system interface and front-end data manipulation. To enable the integration of different data, a unified UML model is developed. The paper explains all steps of 3D reconstruction, BIM geo-referencing, storage of spatial data and visualisation. Special attention is given to the integration of sensors data. The data model and the system architecture are tested for a university campus. The results demonstrate an approach for BIM-GIS-Sensor integration as part of Precinct Information Modelling (PIM). The system architecture allows for a flexible structuring and manipulation of different spatial data towards managing various 3D spatial and non-spatial data.
