This invention discloses a
system and method for constructing earthquake-themed scenarios based on multi-source 3D GIS data, belonging to the field of 3D
geographic information system technology. It aims to solve the technical problems of data silos, limited information display, delayed data updates, and lack of end-to-end
connectivity in earthquake
emergency response. The
system adopts a layered architecture consisting of a data resource layer, a data fusion layer, a service support layer, and an application display layer. The method involves building a basic 3D GIS emergency
scenario, aggregating multi-source earthquake data, achieving spatiotemporal data fusion and
event correlation, and completing integrated 3D display and decision support. This enables unified spatiotemporal fusion and real-time dynamic updates of earthquake data across all dimensions, as well as 3D
visualization and spatiotemporal
simulation of the entire pre-earthquake, during-earthquake, and post-earthquake chain. This provides global and three-dimensional decision support for earthquake emergency command, significantly improving the efficiency, accuracy, and systematic nature of earthquake
emergency response.
