Cyberspace geography is a new research field of cyberspace expression.

Using the relevant theoretical basis of cyberspace geography to build the geographical knowledge map of cyberspace is a new way to improve the overall network security protection ability of the city, improve the dynamic control ability of the regulatory responsible departments, build a comprehensive urban network security prevention and control system, and promote the development of urban network security prevention and control in the direction of initiative, coordination and efficiency. This paper studies the technical scheme of constructing a cyberspace geographic graph from the aspects of element definition, map modeling, data cleaning and construction, and gives the application method of cyberspace geographic graph combined with the comprehensive management and control business of urban network security.
