基于空间信息技术的地震灾害监测评估

摘要

空间信息技术即包括地理信息系统GIS、遥感RS、全球导航卫星系统GNSS以及数字地球在内的地球空间信息科学。随着计算机和空间对地观测技术的发展,空间信息技术已逐渐应用于防震减灾领域。本文通过实际震例分别对目前基于GIS、RS技术的地震灾害监测评估方法进行了分析研究,总结了其优越性以及存在的问题,并结合数字地球平台可视化展示了综合多源数据空间信息技术方法进行的震害评估效果。%Space information technology which includes the geographic information system GIS, remote sensing RS, global navigation satellite system GNSS and digital earth platform, it is an earth space information science. With the development of computer and space on earth observation technology, the space information technology has been applied gradually in earthquake resistance and disaster mitigation fields. This article through the actual examples respectively analyzed the current earthquake disaster monitoring and evaluation method which is based on GIS and RS technology. Sums up the advantages and the existing problems, and with digital earth platform visually shows the effect of comprehensive multi-source data spatial information technology used in earthquake damage assessment.
