Abstract:

     Digital campus has become one of the most important content of digital city construction.  In order to achieve information and resource sharing and to promote college education system and daily education management innovation, it uses geographic space information technology to integrate teaching and research, student life and learning service information, other digital information and resources in digital campus. This paper takes Kunming Metallurgy College Anning campus as research object, using ArcGIS geographic space information technology software as the platform and combining cass digital mapping technology and SketchUp modeling technology to establish three-dimensional digital campus system, which realized three-dimensional virtual digital campus model. As to different object that has different data type, so it proposed different modeling methods. After that, it also adds attributes information to construct three-dimensional model. Finally it realized spatial data access, smooth three-dimensional digital campus roaming and three-dimensional campus information inquiring.

Key words: ArcGIS, three dimension modeling, SketchUp, Arcscene
