摘要
本文讨论了利用陆地卫星、气象卫星和航空侧视雷达等遥感技术进行洪涝灾情监测的技术方法,并应用于1991年江淮地区特大洪涝灾害的快速调查与分析。
Flood hazard is one of the major natural hazards which threaten mankind. Besides the flood control construction, it is also important to the disaster deduction to establish a flood monitoring system. This paper focused on the application of Landsat satellite, meteorological satellite and air-born side-looking radar to flood disaster investigation and evaluation. Based on the analysis of the thematic flood information characteristics of the remotely sensed data, flood inundation area calculation model was developed.This model included digital image processing sub-model, water boundary extraction sub-model, flooding-area calculation sub-model and flood mapping sub-model. The last part of the papsr showed a successful application of the technology to the investigation and evaluation of 'the 1991's flooding in Taihu basin.
