摘要
针对CAD到GIS数据的转换问题,对转换前、转换后以及转换的方法从理论与实践方面进行了探讨。结果表明,为了尽量避免转换后产生的问题,必须对CAD数据进行CAD文件重命名、删除多余要素、CAD图层重新命名、CAD图层提纯以及确定CAD系统等转换前处理。
The paper aimed to study on data format conversion from CAD to GIS, discussing the methods of pre-conversion, conversion and post-conversation at theory and practice aspects. The results showed that in order to avoid the post-conversation problems, pre-eonversion treatment should be done with repeated name of CAD file, deleted redundancy factors, repeated name of CAD drawing layer, purified CAD drawing layer, and confirmed the CAD system by CAD data.
