基于WFS的空间数据共享在地震减灾中的应用
|
摘要
空间数据的不开放性易导致地震减灾部门的各类信息系统形成信息孤岛,对救灾减灾工作造成信息交流障碍。数据共享机制是改善信息资源劣势的有效途径,在Open GIS规范框架下,基于网络特征类服务(WFS)建立了空间数据共享架构,系统以开源软件GeoServer架设服务器,并遵循WFS和GML规范,用户按照通讯协议与服务器端交互,对原始的空间数据文件和信息数据库进行基于特征类的操作,实现灾害数据实时管理。根据该架构建立的系统原型,是应对当前地震减灾需求而建立的开放、实时的减灾救援辅助系统。
Closeness of the spatial data is apt to cause that the diversified information systems in earthquake disaster reduction departments form the isolated information island and the communication bottleneck of the disaster relief and reduction work.The data sharing mechanism is an effective way to improve the information resource poverty.In Open GIS specification framework,we established a spatial data sharing structure based on the Web Feature Service(WFS).The system constructed the server using open source software GeoServer,and followed WFS and GML specification.Users can make an interaction with the server side according to the communication protocols,and can execute operation of raw space data file and information database based on the characteristic class,by which the real-time management of the disaster data can be realized.The system prototype constructed according to the frame,is an open and real-time auxiliary system used for disaster reduction and relief,and it can satisfy the current demand of earthquake disaster reduction.
