| 摘 要： | 结合OGC WPS开放标准规范和分布式检索技术,提出基于OGC WPS构建遥感图像分布式检索系统的方法。采用Z39.50通用检索表达式的扩展模式,避免了遥感图像编目数据库与检索系统的紧密耦合;采用HTTP/XML定义检索网关和资源节点之间的WPS接口,实现了编目资源节点到网关的动态接入与移出机制。最后运用开放源代码GIS技术开发了一个原型演示系统,试验证明上述方法切实可行。 |

| Abstract: | This paper proposes a new method to construct distributed retrieval system for remote sensing images using OGC WPS specification.The common query expression of Z39.50 is adopted to exchange information between gateway and server,so that the retrieval system and remote sensing inventory database are loosely coupled.The catalogue servers provide functions through OGC WPS interface and the gateway is designed as an intelligent agent to understand the metadata of WPS,which makes it possible to dynamically register or un-register server node in gateway.Finally,a prototype system is developed using open source GIS software,and the result proves that the proposed method is feasible. |
