Sensor Web的SOS服务研究与实现
k： an amorphous network of spatially distributed sensor platforms （pods） that wirelessly communicate with each other. Since the standards of Sensor Web is proposed by the open geospatial consortium， the observation service has become the most basic core service specification. The core operation of sensor observation service based on SWE is introduced in detail. The architecture of sensor observation service is designed， including emphasized and data interaction all of each level of the architecture. Finally， technology of java and tomcat to deploy and test the architecture， SOS architecture can be used to deploy the core operations or get real-time or historical observations.Key words： Sensor Web； SWE； OGC； sensor observation service（SOS）0 引言海量信息时代，如何融合异构数据、整合数据、向传感器指派任务、发布订阅和接收预警，以及对传感网络进行管理、互操作等成为棘手的问题。构建一个平台将异构传感网络系统集成在一起，发现数据、融合异构数据、整合数据成为传感网络发展的必然趋势，Sensor Web[1-2]的概念由此被提出来。2005年OGC（Open Geospatial
