Abstract: Smart city is the updated version of digital city. The dynamic implementation of its management services is closely related to the virtual geographical environment. Firstly, the overview of virtual geographic environment is summarized. Then, the key technologies of the virtual geographic environment in smart city is concluded, and 3D dynamic simulation, actual interaction, multi-agent, and the characters digital twin and scope of their application are analyzed. Then the research status and challenges of virtual geographical environment in smart city are analyzed from the perspective of application. Finally, the prospects in the new era of artificial intelligence and VR of the virtual geographic environment in the real-time display, efficient algorithm and actual interaction are concluded.

Key words: virtual geographic environment, smart city, virtual reality, digital twin
