Abstract:
In response to the features of the environment and disaster monitoring and forecasting small satellite(HJ) condition, this paper researches and designs a kind of disaster characteristics information automatic inversion system. According to business requirement of disaster monitoring and early warning, the system adopts B/S architecture and integrates twenty five models of disaster characteristics information automatic inversion, which uses level 2 remote data production of HJ satellite as main input. According to data process relations of these inversion models, a kind of automatic batch process system is designed. Experimental results show it extends HJ star information production chain, and provides real-time information production for disaster monitoring and early-warning. At the same time the system reduces the difficulty of the common users application remote sensing information.
