The Study on 4S Technology in the Command of Earthquake Disaster Emergency

Abstract eng:
With the rapid development of the 4S technology (RS, GPS, GIS, GPRS), the technology has widely been used in many fields (such as urban management, the management of mineral resources, land resource management, etc.). In seismic area, the technology has been successfully used in earthquake monitoring and forecasting and earthquake evaluating. However, in earthquake disaster emergency commanding area, considering the particularity of earthquake disaster emergency, the traditional commanding scheme of earthquake disaster emergency is difficult to adapt the increasingly complex social situation. In this case, the 4S technology can play an important role in solving the problems that exist in the command of earthquake disaster emergency command. The commanding system of earthquake disaster emergency based on the technology will be the trend of the earthquake disaster emergency command system. In this paper, firstly, the problems in the command of earthquake emergency are analyzed, then the role and applied scheme of the technology in the command of earthquake disaster emergency are discussed too. Finally a framework of the commanding system of earthquake disaster emergency based on the technology is presented and some key technologies, such as the design of the earthquake disaster emergency database and application system, are also discussed.
