【Abstract】 By use of technology of Geographical Information System and Remote Sensing which are of capability of comprehensive analysis and real time response, the Natural Disaster Information System is established in this paper. The natural disaster database consists of historic database, environment database and remote sensing database. In the view of natural disaster reduction, the Natural Disaster System is designed with four modules, namely, monitoring subsystem, forecasting subsystem, evaluation subsystem and subsystem for choosing routes to escape disaster.更多还原
