【Abstract】 Earthquake disaster is a natural disaster producing most serious harm to human body and property,so people have paid more and more attention to its prevention and management. Along with the continuous development of science and technology,people in the age of Internet use all kinds of advanced technologies to deal with the earthquake disaster,in which the development of geographic information systems also tend to Web spatial data browse,query and analysis functions combining network technology. A geographic information system based on network technology(WebGIS)has been formed gradually. The appearance of WebGIS platform made the sharing of spatial data to be realized.
