Abstract:

Due to the growing environmental problems, people would pay more attention to their information. But the currently available information display platform is
relatively simple, not intuitive as well. In view of this situation, this paper proposes a dynamic visualization method for the environmental information based on 3D GIS. The
research area is determined by sweepline algorithm, according to cross-validation, Kriging interpolation is adopted, and the interpolated data is processed before released as
KML file, then the data is displayed with Google Earth embedded in a Web page. This paper will take PM2.5 monitoring data in China as an example to demonstrate the visualization
effect, the experimental results show that this visualization method displayed the data directly and accurately, which help users more convenient to understand the current
environmental information.

Key words:  three-dimensional visualization, Google Earth, sweepline algorithm, Kriging interpolation, environment information, PM2.5
