摘要
针对环境与灾害监测预报小卫星(HJ)的载荷特点,设计一种以环境星2级数据产品为主要数据源的灾害特征信息自动反演系统。根据灾害监测预警业务的需求,采用B/S架构,集成25个灾害特征参数反演算法模块,并依据各个反演模块之间的输入、输出流程关系,设计一套自动化批处理流程。实际应用结果表明,该系统能延伸HJ星信息产品链,为灾害监测预警提供实时信息产品,并降低普通用户应用遥感信息的难度。
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.
