基于SOA的遥感影像共享架构研究

Architecture of Remote Sense Image Sharing Based on SOA

摘要: 针对遥感影像数据共享中存在的“信息孤岛”问题,提出了面向服务的共享架构;基于OGC规范扩展定义了可支持计算机搜索、评价并集成数据服务的元信息模型;基于Web Services技术设计和实现了元数据服务和数据服务。实验结果表明,面向服务的共享架构能够集成地理上分布的异构影像数据资源。

Abstract: We analyzed the current status of remote sense image sharing technology.The SOA-based sharing architecture was proposed to solve the problem of isolated information islands.A metadata schema was defined based on OGC specifications to supports search,evaluation and integration of data services via computer application.Metadata services and image data services were designed and implemented.The result shows that the SOA-based sharing architecture is technically feasible to integrate distributed heterogeneous image data resources.
