Research on Visualization of Electromagnetic Environment over Complex Terrain

Visualization of electromagnetic environment over complex terrain is the current development trend of visualization of electromagnetic situation. Visualization of electromagnetic environment requirement is analyzed in this paper, and a method that using electromagnetic data to render radiation area is proposed. Due to the method, visualization framework is also designed. Electromagnetic data need in framework is fast computed by the simplified Longley-Rice model, and together with simulation platform of terrain built by SRTM data, electromagnetic environment is visualized perfectly.
