基于ArcGIS for AutoCAD的空间数据建库方法研究

当前测绘项目生产广泛使用dwg文件作为项目成果输出格式,随着测绘项目成果数量的增多,需建立空间数据库对各类测绘专题数据成果进行科学统一的管理。在基于项目成果dwg文件进行数据建库时,提取dwg中的图形信息的同时还需补充完善图形对应的属性信息。本文提出了一种基于ArcGIS for AutoCAD插件进行空间数据建库的方法,该方法可在CAD环境下实现图形和属性的统一管理,通过ArcEngine进行二次开发,可快速准确实现基于dwg文件的空间数据建库,从而提高测绘项目成果的应用价值。

Research on Spatial Database Building Method Based on ArcGIS for AutoCAD

Dwg file was widely used as the output format of the surveying and mapping project produces at present.With the project amount of surveying and mappingincreasing,it is necessary to establish a spatial database to scientific and unifiedmanage various surveying and mapping thematic data results.When createing the spatial data based on the dwg file,the graphic information in dwg is extracted,and the attribute information corresponding to the graphic needs to be supplemented at the same time.This paper proposes a method of building spatial data based on ArcGIS for AutoCAD plug-in.This method can realize the unified management of graphics and attributes in CAD environment.Secondary development based onArcEngine can realize spatial data based on dwg file quickly and accurately,and the application value of the survey project results was improved.
