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
