The multi-agents mechanism applied in mobile GIS

In our previous work, agent-oriented computing has been used to increase the effectiveness of users in complex application domains of GPS/GIS applications in PDA and smart phone, which use wireless link technology and WindowsCE OS. In this paper, our mobile-GIS system is expanded into handheld devices with J2ME-MIDP kernel, wider range of client devices is supported with GIS/GPS applications. A kit (map DB manager) to convert various formats GIS data of ArcGIS, Mapinfo into our GML document is implemented and geospatial data in GML is described in detail. At the same time, we provide a peer to peer multi-agents mechanism on mobile GIS application, which can distinguish among adaptivity to the specific devices and to user's profile, and realize the geo-data access and update flexibly.
