摘　　要：空间数据库建库流程是数字地质调查系统(DGSInfo)总体技术流程的一个重要组成部分。空间数据库中集合了地质图中所有的地质信息,人们可以通过它很方便地了解各类地质信息,因此建库工作特别重要。本文从空间数据库的基本要素类、综合要素类、对象类属性录入方面概述了建库流程,并对建库过程中的注意事项及技巧进行了阐述。该方法技巧对确保空间数据库数据的质量、提高建库效率有较大意义。The process flow of creating spatial database is an important part in the general technical process of digital geological survey information system （DGSInfo）.Spatial database is a collection of all the geological information of geological maps,and people can easily access to various types of geological information through it,thus it is particularly important to create the database.This paper summarizes the process of cre-ating database from aspect of attribute input of basic element class,integrated element class and object class, and it elaborates on precautions and techniques in the process of creating database.The methods and tech-niques provided in this paper ensure the data quality of spatial database and improve the efficiency of creating the database.
