基于AutoCAD数据建立地理信息系统空间数据库的方法初探

Preliminary Study on the Method of Establishing GIS Spatial Database Based on AutoCAD Data

针对现有AutoCAD数据导入GIS(地理信息系统)空间数据库的需求,在阐述AutoCAD数据与GIS数据特点的基础上,分析了数据库建立过程中遇到的困难及解决措施,提出了3种利用AutoCAD数据建立GIS空间数据库的方法,并将其运用于广东省南海市某县的城市信息化工作,取得较好效果,证明了方法的可行性与实用性。

Aiming at achieving the current demands that AutoCAD data should be imported into geographic information system spatial database, the barriers in the process of database building are analyzed and resolved based on the properties of AutoCAD data and GIS data, and three alternate methods to establish GIS spatial database grounded on AutoCAD data are presented. Moreover, the methods have been successfully applied into the urban inforrnatization of Nanhai City, G-uangdong Province, thus proving the feasibility and utility of the methods.
