Visualization of atmospheric point source dispersion model based on GIS

SUN Qing-zhen ①,DONG Xiao-ma①,REN Zhong-bin②(①Zhengzhou Institute of Aeronautical Industry Management,Zhengzhou 450015,China;② Institute of Surveying and mapping,Information Engineering University,Zhengzhou 450052,China)  
Visualization is a hot topic in geographic field.This paper aimed to solve the main problems existed in visualization of atmospheric dispersion,it integrated atmospheric point source dispersion model with GIS to study the visualization of the point source dispersion.In the paper,firstly it built the point source dispersion model and the integrated framework based on the GIS.Then,it gave the process of the visual expression of the point source dispersion model,and discussed the key question in the realization of visualization.Finally,it gave the results of prediction based on the point source dispersion model to express dynamic effect of the dispersion in practice more vividly.
