Following the development of spatial information acquisition technology, more and more spatial data have been collected through various approaches. There has been a full utilization of geospatial information in emergency management than the past. Increasing demands are being put forward on use of spatial information in emergence system. Recent evolutions in GIS technology and spatial information acquisition technology have led to a more distributed information process and computing environment. "Cloud" technology has emerged as technologies by its focus on large-scale resource sharing and low cost for big data storage technology. This paper proposed an approach which employs cloud-based service to solve the big spatial data technology in emergence management.
