基于Web信息搜索的空间信息门户

Spatial Information Portal Based on Web Information Search

空间信息门户为用户提供一个统一的入口访问分散异构的空间信息资源,是国家空间信息基础设施的重要组成部分。传统的空间信息门户大多采用OGC在空间信息门户参考体系架构中推荐的“发布-检索-绑定”模式,本文提出一个新的基于Web信息搜索的体系架构,并对其中空间元数据自动提取等关键技术进行了研究,最后通过原型系统进行验证。

Spatial Information Portal allows user to access distributed spatial information directly and is one of the most important parts of spatial information infrastructure. A new portal architecture based on Web information search is promoted, which is different from traditional ＂publish-search-bind＂ mode recommended in OGC Spatial Information Reference Architecture. Finally, we develop a pilot system to verify the idea.
