From 3D Building Information Modeling towards 5D City Information Modeling

This paper gives an overview of digital methods currently used for three-dimensional modeling of urban structures as utilized in architecture and town planning. The paper presents new trends in the field of CIM (City Information Modeling), and points to the complexity of problems of planning as seen from the perspective of town planning, indicating the necessity to introduce and visualize the semantic context in 3D modeling at the urban structure level
