| Abstract: | The process of the development of Nankai university virtual digital campus system was given in detail in this paper. The authors adopted an image-based method to obtain the models, which was to extract building models and digital elevation model by high resolution digital aerial photos. On the basis of this, the whole system development work was completed by using the combination of GeoVRML, database and Cortona ActiveX technologies. |
