Geographical Feature Analysis Using an Integrated Graphic Information Processing System

For the effective use of a araphic information processina system, information-integration capabilities are impohant. ~ e r < the information-intearation is defined as an interactive execution of simulationtasks and a database management task. This concept as well as its practical methods are explained in this paper by the introduction of a geographical information system (GIs). The GIs consists of a database subsystem and amlication subsvstems. The database subsvstem executes a daiabase management task, which systematically handles multimedia data including the analyzed results obtained by each application subsystem.he appiication subsystems execute simulation tasks of various aeoaraphical feature analyses usina topographical map data stored in the database. i h e aim of information-integration is to extract new information by the "generation-and-aggregation" method using the above subsystems. As a preliminary experiment, a land route design is explained. The proposed method will be essential for advanced graphic information processing systems in the future.
