摘要
提出了一种基于工作流技术的动态GIS服务链的实现方法,该方法使用抽象GIS服务组合服务链,由GIS服务动态选择机制将抽象服务映射到具体服务,并结合工作流技术,将工作流描述语言描述的GIS服务链流程送入工作流引擎,由工作流引擎管理和监控服务链的运行。
This paper proposes an implementation method of dynamic GIS service chain based on workflow technology. This method uses abstract GIS services composing GIS service chain. The abstract services can be mapping to concrete GIS services by dynamic service finding mechanism. Combined with workflow technology, the process of GIS service chain described by workflow description language can be sent into workflow engine to be executed and monitored.
