Research and Design of Isomerism Distributed Multilevel Spatial Data Center

摘要: 多年来作为国土管理工作重要依据的空间数据不能进行及时有效地更新交换, 上下级之间数据不能同步, 以至各级审批节点只能进行费时、费力的“定性”审批.通过对国土资源数据现状的分析, 提出了树状层次结构数据中心部署模型, 详细分析了数据中心体系模型和数据中心交换模型; 在模型的基础上, 提出了表文件级更新和地理实体全球唯一编码的记录级数据更新方式, 完成了异构数据更新和传输子模块的设计, 实现了多级分布式数据中心之间的数据更新机制.实践表明, 在湖南省国土资源多级数据交换体系中成功应用后, 省厅与长沙市局之间能够远程动态实时交换空间数据, 实现了政务审批工作从定性粗放到定量精细的飞跃.Abstract: The spatial data is the important base of land resource management, but for long time, it cannot be updated and synchronized, lack of valid spatial data, so each level of government can only work at low efficiency mode. Through analyzing the national territory resources data and central data construction at present, this paper proposes a tree structure presenting the deployment, system and exchange models in central data. Data renewal and synchronization are considered through realizing a design of data renewal and a transmission through a sub-module. The entire discussion process has realized a somerism distributional data center. At the same time, we also propose the concept of table renewal at document level and geography entity renewal at record level, which has unique code.
