| 摘 要： | 空间数据的社会、部门、企业的高级别应用的广泛性对日益海量化的空间数据共享提出了更高的要求。元数据是空间数据共享管理与交换的最佳解决方案。XML作为扩展性标记语言已经成为实现元数据描述的代语言。文中结合XML技术描述的元数据设计空间数据的共享管理平台,功能包含数据的检索、基于空间范围和关键字的查询、元数据查看、空间数据集的浏览等功能,实现空间数据的基本交换中心(站),为空间数据的高级别共享提供一种可行的实现途径。

| Abstract: | With the high level usage of huge spatial data in society, departments and enterprises, higher demand is needed to share spatial data with others. Metadata is the best way to fit into the management and share of spatial data. XML, an extended sign language, is the only language to describe metadata. This paper designs share and management system platform of spatial data with XML describing metadata. Its functions include data search, data query by spatial boundary or keywords, metadata view, spatial dataset browsing etc. The platform gives a basic cleaning house of spatial data and applies a feasible way to a high-level data share and management. |
