摘　　要：为较好的实现空间数据从CAD(computer aided design)格式转到ArcGIS格式,最大限度地保留感兴趣信息,以AutoLisp和ArcObjects为基础探索转换方法,提出了一种从CAD到ArcGIS数据转化方法。以层为单元,解析CAD实体内部数据结构,以文本文件为中间媒介,编写从dwg图层到shp图层的转化函数,制作插件嵌入ArcGIS,最后在ArcGIS中检查并分层整饰地形图。该转换方法能快捷方便的实现大批量空间数据转换。To convert spatial data from CAD to ArcGIS while retaining most of original data interest part,this paper puts forward a conversion method based on AutoLisp and ArcObjects developer toolkits.This method first analyzes the internal data structure of CAD entities in layers,then writes conversion functions from dwg layer to shp with text file as intermediate medium,and makes plugin embedded in ArcGIS Desktop,finally it checks data and configures layer in Arc-GIS.The research can provide fast and convenient tool support for large-scale convension.
