传统的单机环境和封闭式网络环境由于有限的资源利用能力,难以充分支持分散地学数据、模型等资源的共享与应用集成。基于网络环境的信息交换特点,提出了分布式地理空间模型共享的服务体系。该体系以数据、模型、元数据等互操作要素为核心,通过网络将数据、模型等网络节点进行开放式耦合。针对地理空间模型服务的互操作问题,提出了分布式环境下的模型共享服务交互接口,该接口定义了模型服务元数据、模型服务的交互操作、模型服务的通讯方式等交互规则,尽可能地降低模型服务与模型终端之间在数据交换、功能调用等方面的互操作困难。为了降低将模型共享为模型服务的实现难度,设计和开发了地理空间模型共享平台,并介绍了在该平台上发布地理空间模型的2种方法。最后介绍了研究成果在Prairie生态模型共享方面的应用实践。 更多还原

【Abstract】 Numerous geospatial computational models have been developed based on sound principles and published in journals or presented in conferences. However modelers have made few advances in the development of computable modules that facilitate sharing during model development or utilization. Constraints hampering development of model sharing technology includes limitations on computing,storage,and connectivity; traditional stand-alone and closed network systems cannot fully support sharing and integr... 更多还原
