IV. CONCLUSION
A smart city is a new round of the informatization in the current world [28]. The sensors are installed in the urban power grid, roads, buildings, pipelines, and other infrastructure to connect into IoTs and combine with the internet. In this way, the interconnection between human society and an urban physical system could be realized. Also, through the establishment of cloud computing center, the personnel, machines, and devices are efficiently managed and controlled to subtly and dynamically manage the urban production and life, and achieve the wisdom state. As a result, it could enhance resource utilization and productivity quality, improve the urban environment and promote the global sustainable development. This paper proposed a government affairs service platform which sufficiently uses GIS and cloud computing technologies to provide a service for facilitating and handling government affairs of a smart city. In future, the system will be implemented according to the top design.
