Dynamic assessment of typhoon disaster condition based on multi-sources remote sensing imagery: Research progress

Natural disaster is the hotspot question in international society and academy. Guard of typhoon disaster is very important since the increasing of its intensity, frequency and extent. Coastal zone is an important area and strategic focus of population concentration, national economy and society development, so the loss from typhoon disaster is very fierce and fatal. At present, the main discussed questions in this field are: remote sensing sources of typhoon disaster condition information, method of disaster condition assessment based on remote sensing imagery, the indexes system and model of typhoon disaster condition assessment, typhoon disaster risk assessment and management. In the background of global warming and quick urbanization, our research should focus on these aspects: the indexes system and dynamic assessment model of typhoon disaster, the RS-GIS tools of coastal zone typhoon disaster risk dynamic assessment and management, mechanism of typhoon disaster information share and distributing management. It can not only realize the quick evaluation and mapping of the situation in disaster area, but also provide scientific foundation for typhoon integrated disaster risk management and the implementation of sustainable development in coastal zone of China.
