Although they can provide a visual analysis platform based on GIS technology, they lack a general description in the extensibility of Web GIS for processing dynamic data,especially real-time data. In this paper, we propose a novel approach for real-time 3D visual earthquake information publishing model based on Web GIS and digital globe to improve the ability of processing real-time data in systems based on Web GIS. On the basis of the model, we implement a real-time 3D earthquake information publishing system—Eq Map3 D. The system can not only publish realtime earthquake information but also display these data and their background geoscience information in a 3D scene.
