摘要
以河南省某县城为例,通过分析高分辨率遥感图像,获取建筑物的属性信息,结合相关调查数据,建立震害矩阵,得到震害预测结果,计算综合地震危险性指数,评价该区域综合抗震能力。与实际调研结果对比后发现,基于高分表率遥感图像的建筑物信息提取技术具有较高精度,能够满足大范围快速震害预测的需要。
Taking a county in Henan province as an example,this paper analyzed the high resolution remote sensing image,got the buiding information successfully,built the damage matrix and assessed the seismic ability under frequent and rare earthquake with comprehensive earthquake risk index.Contracted with the filed survey,the HRRSI method has high precession with low error,which can meet the practical application satisfyingly.The result shows that HRRSI is extremely helpful and promising in the earthquake damage prediction.
