Hierarchical satellite network task planning method oriented flood disasters monitoring in river basins
A hierarchical satellite network task planning method for ground observation tasks aimed at monitoring flood disasters in river basins is proposed.Taking the Chongqing and Chenglingji sections of the Yangtze River basin as experimental areas,through passive and active planning.The results show that this method can provide effective multi-scale satellite collaborative observation information for designated time periods of flood disaster areas in the basin.The proposed method can provide important technical support for timely mobilization of satellite resources,rapid response to flood monitoring needs,and acquisition of satellite data for disaster warning,decision-making,and evaluation.
