The management, and application of spatial data in seamless spatial database is one of the bottlenecks in the development of GIS . This paper proposes a new concept which is called virtual map on the basis of structure analysis and organization of spatial data. Then it introduces the method to organize the spatial data in seamless spatial database .The spatial data can be effectively managed with this method in spatial database.
