In this thesis, a multiagent user interface architecture is designed for the Next Generation Geographic Information System(NGGIS) which supports the following advanced features: multiple users, multiple views, direct manipulation, distribution, and intelligence. In this architecture, agent is a basic functional unit. Agents cooperate with each other by exchanging messages. The User is just a special agent who communicates with any other agents. The ShowCase and its cooperative agents are specialized to present the geographic objects in different views. The WorkShop and its cooperative agents provide a complete interface to allow the user to manipulate the GIS objects directly. The Monitor is specialized to enforce the semantic constrains and control the system consistency. The Interaction Expert interprets multimedia user input and generates multimedia output by driving other agents. The Selector is a cooperative agent of both WorkShop and ShowCase which allows users to select geographic objects with specific constraints.
