Abstract: As a microcosm of digital city and fundamental platform of virtual campus, 3D
digital campus constructions are booming with a new climax. In this paper, ArcGlobe (a
component of ArcGIS) is employed to simulate the 3D campus. By taking Qingdao campus of
Shandong university of science and technology as a case, various data sources and their
corresponding processing methods are analyzed, specific technological route of whole digital
campus simulation is proposed, the creation of 3D digital terrain modeling in different area with
different surface rolling is given, the way to create 3D building modeling specially is emphasized.
Also, LOD and dynamic texture match are illustrated since they raise signally the speed of loading
and drawing. The experiment presented in this paper is proved to be more reasonable and efficient
in 3D digital campus construction.

Key words: ArcGlobe, digital campus, 3D visualization, digital modeling
