基于 GML 的多源异构数据交换技术研究

摘要

以滇池（湖泊）流域生态建设与生态文化数字化信息系统开发为背景，在研究多源异构数据交换关键技术的基础上，利用标准的 GML 数据格式对 SHP 和 MIF 两种不同格式的空间数据进行集成应用，解决了传统地理信息系统存在交互性差的问题，从而实现对空间数据的互操作。实验验证表明，GML 空间数据格式能准确表达两种异构数据的集成结果，从而确定 MIF 和 SHP 两种数据格式成功集成到 GML 框架。%On the background of developing the digital information system of ecological construction and ecological culture of Dianchi watershed,based on multi-source heterogeneous spatial data exchange critical technology,by the standard GML data format to integrate the two different data formats:SHP and MIF,we solve the problem of poor interaction in traditional geography information system to realize the inter-operation on spatial data.The testing result showed that the GML spatial data format can accurately express the results of the two kinds of heterogeneous data.It is successful to integrate the two data formats—MIF,SHP into GML framework.
