摘　　要：随着网络技术和信息技术的发展,空间信息的获取、共享、发布与分析在各个部门的决策中发挥着越来越重要的作用,空间数据的互操作成为地理信息系统领域研究的核心问题之一。本文将探讨基于XML的空间数据互操作与可视化方法,深入比较XML在专业领域中的两种应用标准——GML和SVG规范,结合其各自的特点,具体设计和实践了基于GML与SVG的空间数据互操作与可视化模型系统。实现来自不同GIS平台——ArcInfo、GeoStar、GeoSurf三种软件的空间数据互操作与叠加可视化显示,成功完成了跨平台的异构数据源的数据互操作与可视化研究。With the development of network technology and information technology, the obtaining, sharing, publishing and analyzing of spatial information is playing a more and more important role in the decision of each department. The sharing of spatial data is the key problem in the study of geographical information system. This article discusses about the share method of the space data based on XML, and compares two kinds of application in the professional field of XML deeply --GML standard and SVG standard. Combining characteristics of each of them, the share prototype system of the space data based on GML and SVG has been designed and practiced. It has been realized that the interoperability and the display of superposing melting visually are put to the two-dimensional space data coming form different GIS’s platforms – ArcInfo, GeoStar and GeoSurf. And it has accomplished the interoperability and visualization study of source data coming from different platforms.
