Abstract

In this paper, we will discuss a map synthesis system which handles staticinformation (geographic objects) as well as dynamic information (traffic conditions, weather? etc.). In addition to geographic thesauruses used in the previous systems, we will use co-existence relationships to improve the quality of maps generation. The system is considered to be general purpose (not restricted to car navigation nor travel maps) and can generate arbitrary maps according to the user's specification. It is very difficult for a user to specify a query which corresponds to the required map, because map description is not easy. The system should automatically generate missing information or find errors in the user specification. For the purpose we use geographic domain thesauruses which contain aggregation and other geographicrelationships as well as conventional thesaurus hierarchy. In this paper, we will discuss to use co-existence relationships to enhance ability to select geographic objects automatically. Co-existence specifies relationships among geographic objects which should appear in a map together although they may not have geographic relationship by thesauruses. By utilizing co-existence relationships, a user can acquire much more understandable maps.
