摘要:

当前空间态势可视化方案不能根据快速变化的数据和任务要求实现用户自定义表达。在Web应用领域,Mashup能够将多个不同来源的支持Web API的应用按照一定的模式进行糅合,产生新的Web应用,并利用从外部数据源检索到的内容来创建全新的服务。基于Mashup技术,设计用户自定义的空间态势可视化表达,实现内部Widget之间的数据交互;实现三维和二维态势信息可视化Widget,并能够同步显示空间态势信息;通过网络图层管理进行态势信息的显示管理,实现事件的订阅与发布。实验结果表明,基于Mashup技术的用户自定义空间态势可视化表达能够适应快速变化的任务和数据需求。

Abstract:

Current space situation visualization program cannot achieve user-defined expression according to fast changing missions and data. In the field of Web application, Mashup can integrate a number of different sources of applications supporting Web API by certain mode, which can generate new Web applications, and make use of the contents of the data retrieved from outside to create new services. Based on Mashup, we design a user-defined space situation visualization expression. We can achieve internal Widgets data interaction through the common Widget language and the visual widgets of 3D and 2D situational information, and display situational information synchronously. We manage the situation information display through the network layer management, thus realizing subscription and the release of events. Experimental results show that the user-defined space situation visualization expression based on Mashup can quickly adapt to rapid changing missions and data.

Key words: user-defined, Mashup, visualization, space situation
