摘　　要：随着遥感数据种类和数量的不断增多,用户如何能将丰富的遥感算法模型应用到这些海量数据,从而得到所需求的遥感产品便成为了一个关键问题。针对这个问题,本文引入工作流技术以及面向服务的架构(Service Oriented Architecture,SOA)设计并实现了遥感产品在线定制系统。工作流技术为遥感产品的生产提供了一个从模型表达、管理到运行的完整框架;而面向服务的架构则为系统的建立提供了一个更加灵活、易于扩展和维护的设计方法。实验证明,本文实现的系统能很好地满足用户定制遥感产品的需求,同时保持系统的灵活性。本文所提出的遥感产品在线定制系统能够很好满足多样化的遥感数据生产需求。With the increasing of types and quantities of remote sensing data,how to apply diverse remote sensing algorithm model to such massive amounts of data and produce remote sensing products that meet users' needs has become a key issue.To address this issue,this paper introduces workflow technology and service-oriented architecture(Service Oriented Architecture,SOA)to design and implement a remote sensing product online customization system.Workflow technology provides a complete framework containing model expression,model management and model operation for the production of remote sensing;while service-oriented architecture provides a more flexible,scalable,and maintainable design for system construction.Experiments show that this system can achieve a goal of meeting users' needs properly,while maintaining system flexibility.Finally,the proposed online customization system of remote sensing products can well meet the diverse needs of remote sensing data production.
