基于GIS服务链的遥感影像分布式融合处理

Distributed Fusion Process for Remotely Sensed Images Based on GIS Services Chain

提出了基于Web服务技术、OGC规范和工作流技术,以实现与平台无关的、具备流程编排能力的地理空间处理服务链框架,用于支持复杂的在线空间处理任务。在该框架基础上实现了一个在线遥感影像融合处理示例。该示例展示了利用OGC WCS、WPS,WSDL,UDDI和BPEL4WS等成熟的标准规范来构建GIS服务链,使得客户应用程序能够基于Web服务定制、部署,实现在线的地理空间处理能力。

In this paper, we propose a framework of GIS service chain for geodata and geoprocessing web services to handle complex geospatial tasks in web environment using XML web service, OGC standard and workflow techniques. An online image fusion web service is developed as an example based on the framework. This web service allows different images can be fused on - line. The prototype system integrated industry standards, including Web services, OGC WCS, OGC WPS, WSDL and BPEIAWS, allows invoke geoprocessing functionality in a platform and language independent manner on the Internet.
