NETWORK PLATFORM OF REMOTE SENSING FOR NATURAL DISASTER MONITORING INFORMATION SERVING AND ITS APPLICATIONS

摘要

Natural disaster is an intricate human-Earth interactive system produced by interaction between natural system and human producing & living system. Because of its geographical characteristics and long history, China suffers from natural disasters of excessive categories frequently. Natural disasters have been causing great economic loss and become one of the main factors that stunt Chinese economic development. Remote sensing, Geographic Information Systems and network have their particular advantages and potential in researching on nature disasters. Remote sensing observation data bear the macroscopical trait and the characteristic of comparative high time-efficiency and dynamic-linking, which makes them possible to record the situations of major natural disaster regions repeatedly. The remote sensing satellite sensors also have the corresponding spectrum to different natural disasters. GIS owns the functions of managing, analyzing and model operating the spatial database and system-integrating. Network provides quick channels for releasing information. The integration of these technologies gives an effective support for monitoring and assessing natural disasters. With the support of Remote Sensing, GIS and network technologies, Natural Disaster Monitoring Center, Institute of Remote Sensing Applications and Chinese Academy of Sciences have developed the Network Platform of Remote Sensing for Natural Disaster Monitoring & Information Serving, which has experienced nearly a hundred disasters since its operation in 1996 and has became one of the 14 national websites including the State Council of People's Republic of China. This paper is to introduce this platform's system objective, system structure, system function, natural disaster database and its applications.
