【摘要】 采用了以震中为中心的烈度椭圆的类间椭圆阈值,通过对12322灾情速报平台汶川8.0地震的灾情速报信息的空间经纬度数据进行了空间散点聚类分析,根据此阈值来确定实际的聚类次数,通过聚类来剔除不合理的数据,使得到的最终散点信息真正显示出实际的震情。更多还原

【Abstract】 The inter elliptic threshold of ellipse intensity centered on epicenter is used,and by spatial dispersion of clustering analysis on latitude and longitude data of report information on 12322 damage report platform of Wenchuan M8.0 earthquake,the actual clustering numbers are determined according to the threshold,and remove unreasonable data through clustering to make the final scatter information to show the actual situation.更多还原
