摘要
针对数据集成的传统研究流程(搜集、下载和分析整理数据)中存在的影响研究工作效率、数据本身不能满足研究人员对信息及知识的需求等不足,提出主题式多源信息的实时筛选、综合及加工,与可视化分析的方法。以综合集成平台为基础,水利行业的主题、空间数据为例,结合数字地球技术,运用在线主题式应用的思想,探讨面向服务的多源水利信息集成,以此达到对信息、知识的主题式获取,即在获取信息的同时针对业务需求对其进行加工。在提高数据集成效率的同时加强应用的适用性,同时针对水利信息的特点进行逻辑流程和应用结果的可视化。
Aiming at impacting studies efficiency and that data do not meet the needs of information and knowledge for researchers in the process of data integration for traditional research process（data collecting, downloading, organizing and analyzing）, the article proposes methods of real-time screening synthesis and processing, analysis and visualization of themed multi-source information. Based on comprehensive integration platform, with water industry topics and spatial data as an example, combining with digital earth technology, using the idea of online thematic applications, it discusses service-oriented multi-source water conservancy information integration, in order to achieve the acquisition of subject-type information knowledge. It accesses information and carries on the processing in view of needs of the business also. Improving the efficiency of data integration and strengthening the applicability of application at the same time, it does the visualization of logical process and application results according to the characteristic of water conservancy information simultaneously.
