Research on Cooperative GIS Spatial Data Processing Based on Multi-version Technology and CSCW

摘要

This paper proposes a new mechanisms to realize the multi-user map editing and long transaction of cooperative GIS; based on CSCW theory- and task mechanisms, built the cooperative work model; based on multi-version technology, solved the data conflict during cooperative map editing. Finally, the test of this system is done and the result of the test is given. From the result, we give a conclusion that the test system has reached the aim of the design.
