摘　　要：对空间数据内外业一体化作业过程中数据双向同步技术进行研究。阐述GIS数据双向同步的原理、数据还原原理,提出了基于最优差异化机制的双向数据同步模型,并给出此模型基础上的技术实现案例。实践表明,此方案能很好地解决GIS内外业一体化的数据同步需求。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.
