区域地理空间数据整合技术研究

摘要

The study of geospatial data integration technology is the key technical issues to realize the seamless integration of spatial data sharing online. There are many characteristics of geospatial data, such as multi-resource, heterogeneity,etc. Design geospatial data integration solutions and technical processes based on the ETL of data warehouse. Must be control data quality to ensure to comply with the requirements in each stage in the process of geospatial data integration. At last,with the natural resource database of Fujian for example to explore the application of geospatial data integration solutions and technical processes. Results show that it can provide reference for the practical application.%研究地理空间数据整合技术是实现在网络环境下地理空间数据的无缝集成与共享的关键技术问题.基于地理空间数据的多源异构性等特点,以ETL技术框架为摹础,在数据仓库的整合机制下,设计符合地理空间数据整合要求的解决方案与技术流程,在数据整合过程每个阶段,都必须进行数据质量控制.文章最后以福建省自然资源基础数据库为例对其应用进行了探讨,为实践应用提供借鉴.
