Research and Application on Visualization System of Spatial Electromagnetic Environment

A visualization system of spatial electromagnetic environment was designed and realized. The system realized 2D and 3D visualization of electromagnetic field with electromagnetic distribution situation, isograms, and propagation direction and path. The application result shows that the prototype system can provide the user an efficient visualization tool of spatial electromagnetic environment. This paper solve the model analysis based on the PE method, the establishment of a data visualization mapping model of the geomagnetic field; design space geomagnetic environment visualization system architecture, the design of which the main part of: Geomagnetic set of environmental parameters, unified modeling data analytic mapping drawn rendering, human-computer interaction, and modules; research and the geomagnetic environment visualization of key technologies, including unified model of the space the geomagnetic environmental data, to parse mapping and space method of generating a visual structure, as well as the geomagnetic environment rendering method.
