摘要
国土资源数据交换已经成为国土资源信息化的关键。通过分析目前数据交换的三种常见模式,提出了一种基于GML的数据交换解决方案。采用多级异构分布式的数据组织方案,对数据库的粒度进行了分析,设计了基于GML的数据交换中心架构。最后以湖南省厅和长沙市局为例,概述了数据交换流程。
Land resources data exchange has become a key technology in land resources informationization.According to the three common data exchange model,this paper puts forward a solution to data exchange based on GML.The researcher introduced the data organization scheme which is a distributed multilevel heterogeneous architecture,and analyzed the granularity of database.The framework of data exchange center based on GML was designed.Finally,the data exchange between Hunan department and Changsha Bureau was used as an example to show the exchange flow.
