由于地震造成灾区交通和通讯中断,各部门迫切需要高质量的、及时的空间遥感数据的支持;同时,随着救灾工作的重点逐步向灾后重建转移,各部门都需要及时了解灾区各方面的具体损失情况,指导灾后重建工作。为此,科技部和中国科学院建立了地震灾害空间信息数据分析会商机制,中国科学院对地观测与数字地球中心作为此次灾情遥感监 Due to the disruption of traffic and communications in the disaster-stricken area caused by the earthquake, various departments urgently needed the support of high-quality and timely spatial remote sensing data. At the same time, as the focus of disaster relief gradually shifted to post-disaster reconstruction, all departments needed to know in detail the various aspects of the disaster area Loss, to guide the reconstruction work. To this end, the Ministry of Science and the Chinese Academy of Sciences established a mechanism for spatial data analysis of earthquake disaster data.
