摘要
空间数据的集中式管理模式已经越来越不能满足地理信息产业发展的需求,为提供优质、高效、持续的基础地理数据服务,建设多节点、分布式空间数据是大势所趋,针对维护分布式、多源、异构空间数据的一致性这一亟待解决的问题,从技术层面研究了分布式空间数据库的同步更新技术,提供了一种可行的解决方案,并在湖南省地理国情普查数据应用示范平台中得到了实施验证。
The centralized management mode of spatial data is unable to meet the needs of geomatics industry development. In order to provide high quality, high efficiency and sustainable geographic data service, the construction of multi-node and distributed spatial data is the trend. However, maintaining the consistency of distributed data, multi-source data and heteroge- neous spatial data is an urgent problem. On this basis, this paper studies the synchronous updating technology of distributed spatial database from a technical perspective and provides a feasible solution, which is verified by the geographical condition survey data application platform of Hunan Province.
