滑坡泥石流的多源遥感提取方法
|
摘要
针对汶川地震灾区内滑坡泥石流多发的现象,分析了基于光学遥感数据和SAR数据的滑坡泥石流提取方法。光学遥感数据使用多期影像变化检测和灾后SAR数据使用特征提取的方法,可以分别有效地对滑坡泥石流信息进行提取。结果显示,文中使用的方法可为滑坡泥石流多源遥感监测提供方法参考。
with regard to phenomenon of landslide and debris flow taken place frequently in earthquake area,this paper analyzes extraction method of landslide and debris flow information based on optical remote sensing data and SAR data.For optical remotely sensed data,multi-phase image feature was analyzed to identify the change result from landslide and debris flow;for SAR data,feature analyses method is used.Results show that the method can give a reference to landslide and debris flow identification.
