摘要
随着高分辨率卫星影像成为一种便捷的信息源,遥感技术在震害快速评估中发挥着越来越重要的作用。首先分析了可用于震害评估的遥感数据源,然后总结了近年来国内外利用遥感影像进行震害评估的方法,将其归纳为基于震后影像的方法和基于变化检测的方法,介绍了遥感技术应用在地震灾害评估中的方法,并展望了遥感技术发展趋势。
As the satellite remotely sensed image with high resolution becomes a convenient and rapid information source,it will play an important role in seismic disaster assessment.In this paper,the remote sensing data source which can be used in earthquake damage assessment is analyzed.The methods applied remotely sensed image in post-earthquake damage assessment in recent years are summarized.Meanwhile,remote sensing technology used in earthquake damage assessment is introduced and the developing tendency of remote sensing technology is predicted.
