Abstract(in English)	For the target of map information sharability and consistency under distributed environment, we address a framework for managing multi-levels road networks in distributed environment. Our framework is very powerful to integrate spatial datasets of multi-levels by using inheritance and overlay functions. However, the topological relations among road segments should be computed "on the fly". In this paper, we extend 9-intersection model for this computing.
