AutoCAD扩展属性在规划成果数据库建设中的应用

The Application of AutoCAD Extended Attribute in the Construction of Planning Achievement Database

近年来,规划成果矢量数据汇交要求采用ArcGIS平台的Geodatabase数据库文件格式,而大量的规划项目广泛使用的是AutoCAD的dwg文件作为存储格式,因此基于AutoCAD格式的规划成果数据库建设是急需解决的问题。本文使用AutoCAD二次开发技术,以景德镇控制性详细规划地块入库为例,详细介绍了自定义扩展属性在规划成果数据库建设中的应用,实践表明这是一种可行、高效、便捷的方法。

In recent years,the vector data of planning results require to use the Geodatabase database format of ArcGIS platform,while a large number of planning projects widely use AutoCAD DWG file as the storage format.Therefore,it is an urgent problem to efficiently convert DWG file to GDB file which can be used to construct planning results database in ArcGIS.In this paper,I took the land of regulatory plan as an example to introduce the application of extended attributes in the database construction of planning results by using AutoCAD secondary development technology.Practices show that the method is feasible,efficient and convenient.
