【摘要】 基于大型Oracle数据库管理系统和先进的空间数据引擎SDE技术,将SEG-Y格式海洋地震数据与地理信息系统相结合,并按照"航次-测线-点"的数据组织结构设计了海洋地震数据库。论文首先总结了当前流行的地震数据组织和访问方式,然后阐述了地震数据管理系统的设计方案,最后介绍了数据查询、数据库管理、SEG-Y地震数据查看和地震剖面及与其他地球物理数据综合表达显示功能的实现。更多还原

【Abstract】 We reviewed the popular technologies of accessing and managing seismic data.Then,marine seismic database is designed,based on the features of marine seismic data,the large database management system ORACLE and the advanced technology of spatial data engine(SDE).Through integrating marine seismic data with geographical information system,the paper expatiates on the design schema of seismic data management system and mainly introduces the implementation of functions about the system’s data query and database management.This integration and management method has been successfully applied in the Digital Ocean project.更多还原
