摘要

“5.12”四川汶川 8级大地震发生后，中国国土资源航空物探遥感中心立即采用“赛斯纳”高空遥感飞机，携带高清晰彩色数码相机及先进的POS系统，迅速获取了重灾区的航摄图像数据。本文以震中附近的映秀镇地区为例，简要介绍了以该高质量航摄数据为基础，采用数字滑坡技术，快速进行震后重灾区灾情及次生地质灾害遥感调查的成果。

Abstract：

While the intensive 8 magnitude earthquake happened in Wenchuan，Sichuan province，China，China Geophysical Survey and Remote Sensing Center for Land and Resources go into action without delay and has captured the aerial photo data of serious destroyed conditions and geological disasters surround the seismic area by advanced color digital camera and POS guide and localization system carried by high-altitude remote sensing plane. This paper take Yingxiu Town district where 11.6 km away from the seismic center as an example briefly introduce the results that based on high quality color aerial photo and adopting digital landslide technique to survey the destroy and disasters conditions near the seismic center areas after the earthquake happened.
