地学空间数据仓库的构建技术

Technology for the construction of the geoscience spatial data warehouse.

为了将中国多源、异构、分散的地学数据集中到一起,为资源评价提供有效的数据供应,将地学空间数据仓库作为实现数据集成的解决方案。首次提出了符合中国国情的具有数据源、空间ETL、空间数据存储、基于SOA的应用服务和客户应用的5层地学空间数据仓库的体系结构。根据中国地质行业行政划分和数据的分布情况,设计了能够实现地学数据集成的国家、大区所、省三级管理的地学空间数据仓库系统的物理部署方案。这是一套符合中国地学实际情况且完整可行的地学数据集成方案。

The authors took the geoscience spatial data warehouse as a scheme of data integration in order to integrate multi-source, heterogeneous and disperse geological data of China and provide effective data for resource assessment. They for the first time present a geoscience spatial data warehouse architecture that conforms to China＇s national conditions and have five levels, i.e. the data source, spatial ETL, spatial data storage, apphcation service based on SOA and client application. The authors designed a three-level （state, administrative regions and provinces） physical deployment scheme for the geoscience spatial data warehouse system according to the administration regions of China＇s geological work and distribution of data. It can realize the objectives of geoscience data integration. Research results show that this is a complete and feasible geoscience data integration scheme that conforms to the actual situation of geoscience of China.
