SPATIAL DATA SYNCRONIZATION SYSTEM USING GATEWAY STORAGE IN A DISTRIBUTED ENVIRONMENT AND METHOD OF SYNCRONIZATION

摘要

PURPOSE: A spatial data synchronization system using a gateway changing storage unit in a distributed environment and a method thereof are provided to reflect all changing spatial data while trying to synchronize the spatial data again in the case of synchronization failure, thereby synchronizing the spatial data again. CONSTITUTION: A synchronization device produces a massage having a standard synchronization protocol language type based on changing spatial data having a data language type. A gateway changing storage unit (200) receives the massage. The gateway changing storage unit reads changing spatial data. The gateway changing storage unit stores the spatial data which has been read. If a request for synchronization is received from an external devices, the gateway changing storage unit transmits the changing spatial data to the external device based on the synchronization request.
