Abstract: Based on the Web AppBuilder framework, a campus virtual campus system is built by using the campus of South China Normal University as the research area, which combines ArcGIS Server map service, panorama technology and Cesium three-dimensional engine library. The system implements campus panorama roaming, 3D scene visualization roaming, 2.5-dimensional map information service and other functions. It is proved that the Web AppBuilder framework can implement the integrated development of the virtual campus system and reduce the development difficulty of the WebGIS application system, and greatly improve the development efficiency.
