摘要
大多数GIS应用系统的建设需要基础地理数据的支持,而大比例尺基础地理数据的采集、存储与更新目前普遍基于AutoCAD环境、采用CAD格式,将CAD数据转换为GIS数据花费大且更新时一致性难以保证。本文提出一种将CAD数据与GIS应用环境相融合的新方法,旨在为当前GIS应用中的"数据瓶颈"问题提供一种实用的解决办法。
The GIS application system is surely depended on the fundmental geographic datum which are attached to AutoCAD platform and stored on CAD format. It is cost vast transforming datum from CAD to GIS ,furth more, GIS Datum must be keep consistent with CAD ones when the last is updated. A new method about data fusion of CAD Datum and GIS ones is supported in this paper to resolving this problem.
