摘要

摘要: 针对地震活动性研究对空间可视化软件的应用需求，研制了基于Web服务的地震活动性分析平台。设计了系统的体系结构，采用开源的WebGIS服务器Geoserver和OpenLayers客户端技术，实现了WebGIS服务与Web服务的集成。系统在B/S模式下工作，用户通过浏览器使用系统提供的服务，提供交互式图形用户界面，地图配置选项，区域选择工具、测距工具等。支持对地震进行空间和时间维度的分析，实现了地震、断层、政区等多种地理要素的空间可视化；利用WebGL技术实现了断层的3D模拟；支持多种地震参数时间序列分析方法；提供对图层进行配置、控制、选区和测量的功能接口；提供了丰富的交互式属性查询接口。

Abstract: According to the requirements of spatial visualization software applied to the research on seismic activity, a platform based on Web services is developed and its architecture is introduced. Geoserver is used at the server end and OpenLayers at the client end to achieve the integration of WebGIS and Web service. The system supports analysis at both spatial and temporal dimensions for earthquakes. It supports many functions as following: ① Spatial visualization for various geographic elements such as earthquakes, faults, political districts and etc.; ② 3D simulation of faults with WebGL is supported by the system; ③ Popular time-series-oriented methods for seismic activity; ④ Interfaces for configuring, controlling, selecting, and measuring of geographic layers; ⑤ Interfaces for interactive querying.
