Abstract
An overview of Building Information Modelling (BIM) and Geographic Information Systems (GIS) is presented, where BIM and GIS are distinct and shared characterisitics are examined. Both BIM and GIS involve realistic modelling through digital data. Nevertheless, BIM and GIS models these data differently, with varying scope and scale for representation of world objects to accommodate various envisioned applications. Recent research on the use of BIM and GIS in smart cities recommend the integration of both, for the many technical, administrative, economic, and environmental benefits. The paper highlights the challenges for integrations, along with possible integration schema and applications of BIM and GIS in smart cities.
