摘要
地震核查技术是《全面禁止核试验条约》规定的主要针对地下核爆炸监测的国际监测技术手段.为了提高对低震级事件的检测、定位与识别能力,开发了禁核试核查地震信息系统.该系统以ArcGIS为基础,充分发挥GIS的强大的空间数据分析、拓扑分析和数据可视化处理能力,为地震数据的分析处理建立灵活方便的图形化研究环境.利用ArcSDE Geodatabase数据模型与大型关系数据库管理系统ORACLE相结合,并通过基于COM的Arc Objects组件开发技术扩展ORACLE的管理功能,真正实现了空间、非空间等多源数据的一体化无缝集成,并保留了ORACLE的海量数据管理、事务处理、记录锁定、并发控制、数据仓库等功能.本文主要论述禁核试核查地震信息系统的总体设计与相关技术.
Seismic monitoring is one of the most important approaches for ground-based nuclear explosion monitoring. In order to improve the monitoring capability for low magnitude seismic events, a seismic information system was developed by using the technologies of geographic information system and database. This paper describes the designing and critical technologies of the Seismic Information System in CTBT Verification developed based on ArcGIS and ORACLE platforms. It is a combination of the database storage framework, application programming interface and graphic application software for users to meet their monitoring objectives. Combining the ArcSDE Geodatabase, RDBMS ORACLE and ArcObjects developing technique on COM, not only the multi-sources data has been seamlessly integrated, but also the most functions of ORACLE, for example: consistency, concurrent access, security mechanism, etc, have been reserved. For easy access to the in formation system we develop two different mechanisms. The first is a menu-driven internal system that is run on NT platforms. The second access mechanism is based on LAN and easily accessible by any web browsers.
