| Abstract: | This paper mainly makes a study on GIS data bi-directional synchronization technology, during the integration internal and external trade operation. Elaborated the principle of GIS data Bi-direction synchronization, data reduction principle. Proposed bi-directional data synchronization model based on mechanism of optimal differentiation, given cases of technical realization based on this model. Practice has proved that this program can be a good solution to meet GIS data synchronization needs for integration of internal and external trade. |
