摘要：

In order to more efficiently manage and display the Internet public opinion information about natural disasters for the serious natural disaster relief decision support, a kind of geospatial grid display method based the global subdivision grid is presented. By extracting the location information of the Internet public opinion information about natural disasters, the related disaster information can be identified and displayed in the global subdivision grid framework of the GeoSOT. By this method, it can achieve the information statistics at different grid scale and be helpful to improve the fast location positioning and service of the Internet public opinion information about natural disasters.
