The application scheme of Google Earth in China's earthquake emergency command work can be taken as follows: producing and loading regional map, then issuing public earthquake information; navigating and tracking the rescue routes combined with GPS; establishing three-dimensional model according to information at the scene, and displaying the changes of three-dimensional scene of earthquake disaster area. This application is useful to the reform of China's earthquake emergency command.
