Abstract:  With the increasingly severe global environmental climate, it is urgent to provide decision support for relevant government departments to protect the environment and social development by means of environmental information. Environmental quality data visualization and visual analysis technology play an important role in the process of environmental information. In this paper, the design and implementation of the system function and architecture are introduced from the point of view of visualization and visual analysis, and the key technology of the system is discussed. The results show that, the system in visual modeling, two or three dimensional visualization, data organization of the environmental quality of multi-source data and data scheduling, 3D scene real-time rendering and other aspects have special solutions. The system can display the information of environmental quality data in all directions, and realizes the analysis of multi-source environmental quality data.

Key words: visualization, visual analysis, environmental quality data
