一种环境质量数据可视化与可视分析系统

Visualization and Visual Analysis System of Environmental Quality Data

随着全球环境气候的日益严峻,迫切需要通过环境信息化手段来为政府相关部门在保护环境、规划社会发展等方面提供决策支持,环境质量数据可视化与可视分析技术在环境信息化过程中起着举足轻重的作用。本文主要从可视化和可视分析的角度介绍所设计和实现的系统的体系结构和功能,并对系统的关键技术进行重点讨论。实例结果表明,该系统在多源环境质量数据的可视化建模、组织方式和数据的二三维可视化展现以及数据的动态调度、三维场景的实时渲染等方面都有独特的解决方案,系统可以全方位地展现环境质量数据中的信息,实现对综合多源环境质量数据进行分析。

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,3 D 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.
