Research on information system for natural disaster monitoring and assessment

The serious natural disasters such as flood and earthquake result in great loss to human every year. It is of great significance to monitor and assess the situation of a disaster with information system based on GPS, RS, GIS and so on. In this article the construction of information system for serious natural disaster monitoring and assessment is studied, which uses the dynamic GPS, Airborne SAR, GIS, parallel computation remote sensing image processing technology and so on. The whole system can be divided into two parts, i.e. the air part and the ground part. The prominent advantage of the system is its approximate real time processing of the disaster situation information. We introduce the elements of the two parts and their function in the system in detail. And the key technology to implement the quick image processing is also introduced in detail. At last the application efficiency is introduced.
