Traditional electronic map, which is based on ArcGIS API for Flex, just navigates to the geometric center of the target building, but the positioning accuracy of the specific unit inside the building is not enough. To update and maintain spatial data, administrators must resort to map editing software as well as ArcGIS Server. Further more, with 360-degree Virtual navigation in the digital campus becoming a research hotspot, massive data will inevitably increase the burden of the system and reduce the loading speed. To this end, in this article we proposed a method on the precise geolocation network using, in order to make the positioning more accurate. While processing linear road data, we don't have to consider the relationship among real targets but refine the original linear vector layer and stored this layer and other linear layers separately. The latest version of ArcGIS supports the Feature Access, the ArcGIS API for Flex provides online editing tools to achieve the online map editing purposes. To reduce the size of the project, the real data on the server should be stored separately and the address link recorded and called when the application is running. In order to achieve better interaction with the digital campus, we adopted technology of RIA (Rich Internet Application) and built the digital campus system of Shandong University of Science and Technology based on ArcGIS Server and ArcGIS API for Flex. The system realized functions of geocoding address, querying, the shortest route analysis, online map editing and 360-degree virtual navigation. In this paper we focused on the key technologies on data arrangement, generation of 360-degree data and programming of the project. The successful experiments show that the precise geographical positioning network method, the separate management of the real data and online map editing are feasible.
