A new technology roadmap was proposed for implementing a 3D digital campus system. After intro-ducing conceptions of relative knowledge background, this paper made an elaboration of two critical constituent parts of the technology roadmap, i.e. an optimization approach to 3D model building based on Keyhole Markup Language and system architecture for 3D digital campus based on virtual globe application programming inter-faces. Finally, a 3D digital campus system for Lanzhou University was been implemented as an experimental case, which can be visited online by web users and has rich functionalities, such as browsing in 3D scene, locating, searching for geographical information, etc. This 3D digital campus system is featured by a smooth roaming and expedient development. In conclusion, the technology roadmap based on KML and virtual globe technology for 3D digital campus system is feasible and practical and possesses advantages in the aspects of model optimization and lightweight architecture.
