| 摘 要： | 本文利用格网技术(Fishnet),对龙门山地区"5.12"大地震震后的多期次遥感影像数据及基础地理信息数据进行评价、整合并实现了动态管理,在此基础上得到覆盖整个龙门山构造带的、能够反映不同地物信息的影像群.汶川地震造成了大量山体崩塌、滑坡、泥石流等地震场地灾害,这些灾害体表现为成群、成带分布的特征,并且单一的小灾害体...

| Abstract: | Based on Fishnet technique,by implementing data estimate,data integration and dynamic management to remote sensing images after Wenchuan Earthquake and to basic geographical information for Longmen Shan region,we got a cluster of remote sensing images which can cover the whole Longmen Shan region.Because the distribution of field damages mainly shows in group and in strap,so,slight field damages,although can not be interpreted accurately from a remote sensing image,their summation occupies a considerable ar... |
