联合LISP和FME实现DWG到SHP的带属性转换

AutoCAD具有强大的图形绘制功能,SHP作为ArcGIS平台最常用的数据格式,可以为几何的点、线、面数据赋予必要的字段属性信息。本文首先通过LISP语言对AutoCAD进行二次开发,实现对所绘制的几何数据追加扩展属性数据,再通过FME软件实现DWG数据到SHP数据的带属性转换,解决以往两种平台之间数据属性无法衔接的问题,提高了工作效率。

Format Conversion from DWG to SHP with Feature Attributes Based on LISP and FME

AutoCAD has powerful graphics rendering function.Shapefile as the most commonly used data format of the ArcGIS platform can give the necessary field attribute information to the geometric point,line and surface data.This paper first conducts secondary development on AutoCAD through the LISP language,appends the extended attribute data to the drawn geometric data,and then realizes the attribute conversion of the DWG data to the SHP data through the software.It solves the problem that the data attribute can not be connected between the two platforms in the past and improves the working efficiency.
