摘　　要：当前,海量的多源异构应急测绘数据在数据发布服务方面具有发布操作繁琐、发布效率低等问题,对此,本文研究了集成规则的应急测绘数据批量发布方法,实现海量应急测绘数据的快速发布。首先,分析应急测绘数据的类型及结构特点,采用虚拟数据库法集成方案实现应急测绘数据集成。然后,设计发布规则、构建规则库,通过匹配规则计算集成匹配的各发布规则形成发布规则实例集,接着通过解析实例集中的规则实例获取发布数据接口各参数值,最后执行接口实现多源异构应急测绘数据的批量发布。本文以面向服务架构设计洪灾应急测绘数据发布原型系统,实现洪灾应急数据的批量发布。实践表明,该系统能为用户提供统一、灵活、快速、实用的数据发布服务,实现应急测绘数据的发布共享。At present,massive multi-source heterogeneous emergency surveying and mapping data has problems such as cumbersome operations and low efficiency in data release services.In this regard,this paper studies the method of batch release of emergency surveying and mapping data with integrated rules to realize the rapid spread of massive data.First,we analyze the types and structural characteristics of emergency surveying and mapping data,and use the integration scheme in virtual database method to achieve integration of emergency surveying and mapping data.Then,we design release rules,build a rule library,calculate and integrate the matched release rules to form*a release rule instance set,then parse it to obtain the parameter values of the release data interface,and finally we execute the interface to achieve batch release of multi-source emergency surveying and mapping data.Taking as an example,this paper uses a service-oriented architecture to design the flood emergency surveying and mapping data release prototype system.Practice shows that the system can provide users with unified,flexible,fast and practical data release services,and realize the release and sharing of emergency surveying and mapping data.
