Abstract
In order to more rapidly and effectively obtain the geospatial location and quantitative distribution of the trapped people who are under the ruins or besieged by special serious natural disasters, such as earthquake, flood and landslide, a kind of natural disaster emergency rescue system based on the mobile phone's high-precision positioning of the trapped people is put forward. Being integrated with the mobile phone positioning, mobile cellular communication, BeiDou satellite positioning and short message communication and 3D geographic scene technologies, this system can apply to the condition of the ground communication interruption and monitor the positions of trapped people and the rescue process in time. And it is by the three-level administrative application platforms that are respectively deployed on the ministry-level, the province-level and the disaster site that the on-site emergency rescue information collaboration is achieved so as to be helpful to improve the ability of the serious natural disaster emergency rescue and relief decision support.
