用中国环境减灾卫星1号数据评估日本仙台9.0级大地震引发海啸淹没区

摘要：

Damages caused by earthquakes are hard to detect with medium spatial resolution satellite data.However,the magnitude 9.0 Japan earthquake occurred on March 1 1,2011 has caused a devastating tsunami.The tsunami pushed widespread flooding over the coast of eastern Japan.If satellite data can be obtained at the time of tsunami flooding,it should be possible to map the submerged coastal area.Unfortunately,today's technology is still far from perfect to allow acquisition of detailed enough satellite data at the right time of a disaster.地震对平坦地区引起的损失用中等分辨率的卫星数据比较难于辨认.但是,2011-03-11在日本仙台发生的9.0级大地震引发了巨大的海啸.海啸造成日本东北部近海岸带的低洼陆地巨大的淹没损失.如果能及时获取当时海啸淹没的遥感影像,应该能够获得比较准确的淹没区制图.但是,我们能够获得的资料仅仅是地震发生以后3天的中国环境减灾卫星1号的多光谱成像数据,我们报告利用这份资料获得的淹没区的制图结果.
