【摘要】 为实现不同比例尺地震应急数据的融合与集成,在分析城市地震应急数据库功能的基础上,设计了基于多比例尺空间数据库技术的南京市地震应急数据库框架。论述了其中不同尺度基础地理信息数据的处理、转换方法,以及多比例尺基础地理信息数据的融合建库方法。接着阐述了地震应急专题数据库的设计和与多尺度基础数据的联接。最后通过开发南京市地震突发事件救灾应急平台,展示了多比例尺应急数据库在地震应急平台中的应用。更多还原

【Abstract】 In order to realize the fusion and integration of multiplescale earthquake emergency data,and based on the analyzing functions of urban earthquake emergency database and the framework of multi-scale spatial database technology,Nanjing earthquake emergency database is described.Processing and transformation method of different scale foundation geographic information data in this database are discussed,and the fusion and building database method of multi-scale foundation geographic information data are expounded.Design of earthquake emergency thematic database and connection process with multi-scale foundation data are set forth.Finally,Nanjing earthquake emergency platform is developed and the application of the multi-scale database is shown in this emergency platform.更多还原
