排水管网CAD数据导入ArcGIS的方法研究

Study on the method of importing drainage network CAD data to ArcGIS

通过对ArcGIS直接导入法的优化,完成了巢湖市部分排水管网CAD数据向ArcGIS数据的转换,解决了数据转换过程中容易出现的图形要素不一致、坐标不准确、属性信息混乱、拓扑关系错误的问题,并结合Access软件对属性数据进行了修改和补充,为后续的ArcGIS空间分析工作提供了条件。

The conversion of CAD data to ArcGIS data was completed for some drainage network in Chaohu City by optimizing direct import of ArcGIS. Some problems such as inconsistent graphical elements, inaccurate coordinate, chaotic attribute information and incorrect topology were solved in data conversion process. Also, the attribute data was modified and added combined with Access software, which provided the condition for subsequent spatial analysis of ArcGIS.
