针对当前的一般在线遥感处理平台中存在的数据共享形式单一,难以实现应用场景的共享;细粒度处理服务的共享与描述不足以满足复杂遥感业务的整合需求;缺乏有效的交互模式及良好的用户认知体验等问题,该文提出了一种SOA环境下的基于弹性业务的在线遥感应用框架。该框架实现了数据/服务的搜索及应用环境模拟的功能实现了数据、服务、应用的多层次的共享。该框架也使用的弹性的业务逻辑组合方法和“热插拔”的模式较好地满足了复杂的业务需求,同时框架采用了富客户端技术,给用户提供了较好的使用体验。最后,通过一个遥感分类处理实例说明了该处理框架的有效性和可行性。
For the current general online remote sensing processing platform exists a single form of data sharing, sharing of scenarios is difficult to achieve; the sharing and description of fine-grained services are not sufficient to meet the integration needs of complex remote sensing services; the lack of effective interaction modes and good users Cognitive experience and other issues, this paper presents a SOA environment based on elastic business online remote sensing application framework. The framework realizes the data / service search and application environment simulation to realize the multi-level sharing of data, services and applications. The framework also uses flexible business logic combination method and hot swappable model to better meet the complex business needs. At the same time, the framework uses rich client technology to provide users with a better user experience. Finally, an example of remote sensing classification is given to illustrate the effectiveness and feasibility of this framework.
