国土空间数据融合发布系统的设计与实现

Design and Implementation of National Land and Space Data Fusion and Publishing System

针对当前大多数地图服务器数据组织形式各异以及缺少统一服务自动发布的调用方式问题,基于PostgreSQL+MongoDB数据库,结合动态矢量切片技术、三维数据分块存储技术等关键技术,实现海量多源异构国土空间数据的入库即发布、数据服务融合管理、服务协同共享等能力,构建了国土空间数据融合发布系统。实际应用表明,该系统打通了数据服务发布后即可支撑业务应用的高速通道,为国土空间二三维数据的存储、管理、发布、共享提供了有力支撑。

In response to the diverse data organization forms and lack of unified service automatic publishing invocation methods in most current map servers,a national land and space data fusion publishing system has been constructed based on PostgreSQL+MongoDB database,combined with key technologies such as dynamic vector slicing technology and 3D data block storage technology.The system has achieved the ability to store and publish massive multi-source heterogeneous national land and space,integrate data service management,and collaborate and share services.Practical applications have shown that the system has opened up a high-speed channel for supporting business applications after data service publishing,providing strong support for the storage,management,publication,and sharing of national land and space 2D and 3D data.
