Capacity Analysis Of Gf-4 On The Disaster Management

Satellite remote sensing can provide repeat and detail observatio, which has played an important role on the disaster management. Different with the existing satellites, GF-4, which works on the geosynchronous orbit and carry on a camera with 50 meter spatial resolution in visible and NIR bands, can give a continuous earth observation. It is the highest spatial resolution among the civil satellite on the geosynchronous orbit, and have 4 operation mode: general, continuous, regional and maneuvering, which is very suitable for disaster management. In this paper, based on those characteristics of GF-4, the capacity for disaster management in disaster risk analysis, emergency response, disaster loss and recovery assessment was analyzed. It would be very useful for the rapid emergency monitoring on drought, flood, snow disaster and forest fires and can be important complement data source for the risk analysis, loss and recovery assessment.
