Abstract: In order to solve the problems in the traditional multi-person collaborative update technical solution for massive basic geographic information data, and meet the requirements of operation efficiency and process data management in actual production, this paper proposes a multi-person offline collaborative operation method, which is extended based on the spatio-temporal database model, through the centralized storage and management of multi-temporal data during the update process, offline feature editing and collaborative state maintenance, collaborative conflict detection and processing, and local editing content submission, etc.,multi-person offline collaborative update operations are realized. A collaborative production operating system has been developed based on this method, which has been applied in a number of provincial and above database update projects with good application effects.

Key words: collaborative operation, spatio-temporal database model, basic geographic information data update, incremental extraction
