摘要
通过分析借鉴当今服务链技术与工作流技术研究成果,充分考虑地理信息数据量大、数据源异构性的特点,对适于地理信息服务链的过程建模方法、过程定义语言、建模工具以及工作流引擎的体系结构、调度算法、应用框架进行重新设计,实现了地理信息服务的可视化组合建模和服务链的自动执行。
Through analysis and references of advanced achievements of the service chain and workflow technology,thinking of the characteristics of large amount of geographic information datas and heterogeneity of data sources,workflow management system which is suitable for the geographic information service chain,including the process modeling method,process define language,modeling tool,model structure,adjusting measuring method and application framework of workflow has been redesigned.It has realized visual combination of geographic information services and the chain＇s automatic performance.
