摘要
在现代信息技术和空间技术高速发展的今天,区域地质调查工作过程的数字化已经成为一种必然趋势,它能更好地实现信息共享和数据更新,为地质工作服务.区域地质图空间数据库的建设为基础地质调查规划部署、地方资金找矿勘探提供了重要的数据支撑,是地质调查成果数字化、信息化及国土资源部数字化工程的重要组成部分.通过对数字地质图空间数据库的组织模型、空间存储及属性继承、辅助建库工具、质量监控的阐述,为建库提供了技术保障,保证了数据的精度,有效提高了建库效率.
With the rapid development of modem information and space technology, the digitization of regional geological survey has become an inevitable trend, which can achieve better information sharing and data update for geological work. The analysis on the architecture model of digital geological map spatial database, space storage, property inheritance, auxiliary tools for database building and quality monitoring is proposed, which offers technical guarantees for the building of spatial database and accuracy of data and improves the efficiency of spatial database building as well.
