基于REST架构模式的遥感影像数据服务设计

Design of remote sensing image service based on REST

将表述性状态转移(REST)架构模式应用到遥感影像数据服务,提出一种基于REST架构模式的遥感影像数据服务方案。首先探讨了基于REST架构模式设计遥感影像数据服务的关键环节,然后分别从影像服务资源实体识别、影像服务资源标识、影像资源表述、影像资源操作等方面进行了详细阐述,最后以WCF框架为基础说明了遥感影像数据服务的实现要点。结果表明,REST架构模式是设计遥感影像数据服务的可选模式。

This paper proposed a scheme of Representational State Transfer （REST） image service based on the REST architectural style. First of all, the pivotal points of REST image service were discussed. And then, the specific steps of the image service were formulated from the following aspects： identification of resources, resource identifiers, resource representation and resource operation. Finally, the essentials on how to implement it under WCF were provided. The result shows that REST image Web service is feasible.
