地震目录数据动态可视化处理服务系统

System of dynamically visualized service for seismic catalogue data

为数据共享项目研制和构建了一个具有一定实用价值的动态地震数据处理及可视化服务的系统,并简要介绍了该系统的网络编程模式选取,且选择ISAPI模式作为实现服务平台的编程模式。详细分析了Internet动态服务平台的设计及实现,包括服务平台编程语言的选取、系统的运行环境、后台的数据库支撑及技术流程等。通过SQLServer数据库存放和管理用于动态可视化服务的地震目录数据和地震序列目录数据。在数据库中共存放中国强震目录4227条和中国小震目录188033条以及7个地震序列目录共计50072条。最后,着重介绍了该服务系统的主要功能,包括地震目录服务功能和地震序列分析处理功能。

A dynamically visualized service and seismic data processing system that can be used for data share was developed and constructed in this paper. The choice of network programming mode in this service system is briefly introduced, and ISAPI (Internet Server Application Program Interface) technique mode is selected to realize dynamic service. The design and realization of dynamically Internet service including the programming language, running environment, database and the technical flow, are presented in detail. Seismic catalogue and seismic sequence catalogue used for dynamically visualized service is stored and managed by Microsoft SQL Server Database. In this database, the items of the strong earthquake, micro-earthquake and 7 seismic sequence catalogues are totaled up to 4227, 188033 and 50072 respectively. As a result, the key functions of this service system are emphatically listed in this paper, including seismic catalogue service and seismic sequence data analysis and processing.
