The city management based on smart information system using digital technologies in China

Scientific planning, digital management of construction and intelligent service are needed for a smart city. This paper focusses on city management based on the smart information system and digital technologies in China. The establishment of the smart intercommunication system of landscape, water conservancy, environmental protection and other industries is basic for a smart city. This paper introduced a framework of digital technologies for the construction of a smart city, which made full use of the city information modelling based on the geographic information system, building information modelling, internet of things, and integrated digital system and service platform such as satellite remote sensing, global navigation satellite system, mobile applications, cloud computing, visualisation technology etc. The study of the case implemented show that the framework is applicable to the smart city with digital technologies that includes the data model and system, integrating the urban basic geographic data, and data of infrastructure and other public facilities related to traffic, urban construction, 'One Map' of land and resources etc. The governance is more effective through data acquisition, data transmission, data analysis and processing based on the data platform and system.
