智慧城市空间信息公共平台：城市数据价值之源

In recent years, with the rapid development of various types of sensing technology, humans have achieved unprecedented high-frequency monitoring of various types of urban data. The collection, aggregation, sharing, management, integration, analysis, application and service of multi-source data can effectively reduce the energy consumption of urban resources and improve the efficiency of urban management. It becomes the core concern of urban managers and the public. Taking the construction and related applications of the spatial information common platform of Sino-Singapore Tianjin Eco-city as an example, this paper systematically introduces the core role of the spatial information common platform in the construction of smart cities. Furthermore, the urban data system and the aggregation, collating and fusion is elaborated. Based on this common platform and these multi-source urban data, a set of single-index and comprehensive-index urban pulsation analysis methods are proposed. Finally, the future development directions of smart city practice in data sharing, analysis and application services are prospected.
