Abstract
The construction of city information modelling (CIM) is of great significance for the formation of a new smart city. In this paper, on account of UAV tilt photography, BIM model, Internet of things traffic data, to build a CIM platform under multi-source data, a pilot study was carried out in Tiexi New City. The development platform of Terraexplorer Pro based on the Skyline system is combined with the main technical support of BIM, GIS, and IOT to construct CIM. Its purpose is to achieve static and dynamic, ground and underground, indoor and outdoor integration, and provide prospects for future urban evolution. This study can contribute a reference for other CIM planning, and equip an effective scheme for smart city system planning and urban governance.
