基于ASAR和ETM影像的洪水淹没分析

MONITORING OF FLOOD DISASTER AREA BASED ON ENVISAT ASAR DATA AND LANDSAT ETM DATA

利用了星载的雷达系统ENVISATASAR汛期数据,结合汛期前的ETM图像,得到了不同时期水体的变化范围,实现了洪水淹没范围的研究。

We take advantage of radar data which was received in the flood period by the most powerful satellite-borne radar system-ENVISAT ASAR,to compose an image with the Landsat ETM data that was accepted during non-flood period.Then the changed areas between the blood and non-flood period through contrasting the composite image are analyzed.
