EOS-MODIS数据监测暴雨洪涝灾害的技术方法

The Technical Methods of Monitoring Flood Disaster Due to Torrential Rain Using EOS-MODIS

摘要: 简述了EOS-MODIS数据用于监测洪涝灾害的优点;采用EOS-MODIS的可见光和近红外波段的比值模式识别水体信息;通过比较位于江汉平原的长湖的2007年遥感估算面积与实际面积,对水体识别精度进行了检验。在此基础上,归纳出EOS-MODIS洪涝

Abstract: The advantages of EOS-MODIS data for monitoring flood disaster are firstly introduced.The information of water body is identified from MODIS images based on the ratio of NIR(near infrared) to VIS(visible light).T
