Smart cities in China have recently developed rapidly and the number of smart cities is increasing. The top layer design is a guarantee of healthy and efficient construction of the smart city. In order to strengthen the smart city top layer design in terms of management, rationality, and implementation, a management process is developed in this study for all level adminstrative smart city management departments. Moreover, research on visualization of the top layer design is also carried out. To change the traditional text form, an instant, interactive information presentation for smart city top level design is proposed which can help users understand and grasp the content of the design. On the basis of previous researches, a management and visualization system is finally developed to realize the whole management cycle of top level design including filling, reviewing, evaluating, querying and displaying. The system can greatly improve the management and visualization ability of the smart city top level design.
