【Abstract】 Through the introduction to VGI characteristics,illustrated the significance and method of earthquake disaster information,and VGI- based collection process of earthquake disaster information was discussed. Classified earthquake disaster information and illustrated the significance of collection of earthquake disaster information based on VGI. To perfect the theory system of it,VGI- based upload,storage,release,management methods were described. VGI- based information specification of earthquake disaster information,current VGI- based collection of earthquake disaster information problems and trends were discussed,so as to lay a reliable foundation for earthquake emergency decision- making and disaster information publishes.更多还原
