Abstract :
In this paper, agent-based architecture has been introduced into GIS for interactability and scalability. We have developed an interface agent to interactively assist the user with the query formation process. The interface agent has a capability of offering domain knowledge that is associated with a given query. Also the agent records users troubleshooting experience and show them to the same user and other user as hints. Further, we also have developed the agent-based architecture with a 2-tier mediator model in GIS to meet the needs for interoperability among diverse application domains and integration of heterogeneous information source. Also broker agent provides a matchmaking service to other agent. As a result, qualitative and quantitative data can be integrated into GIS. Also we describe a prototype system, GXGIS, using agent-based technology
