洪涝灾害灾情分析和评估的遥感方法研究
The Evaluation of Flood Disaster Damage Based on Remote Sensing

摘要: 探讨了基于遥感和地理信息系统手段进行洪涝灾害灾情分析和损失估计的途径,研究了利用灾后一定时期内的遥感影像再现淹没状况的方法。Abstract: The method for the evaluation of flood disaster damage based on remote sensing is discussed. The remote sensing and geographic information system are combined to analyze the damage situation and derive the necessary information such as the submerged area and volume. Finally the derived information is used for the estimation of the crop (rice) yield decrease. The experiment is completed on REDAS/Imagine and ARC/INFO software systems.
