中文摘要：

通过对MapGIS供水管网数据和ArcGIS Geodatabase数据模型的分析，提出了一种将MapGIS供水管网数据转换到ArcGIS平台的方法。该方法通过对图形数据和属性数据的统一处理，及对ArcGIS几何网络构建中捕捉容限和要素级别的合理设置，使得管网数据的转换准确、操作简捷。应用实例表明，经该方法转换得到的ArcGIS管网数据与原管网数据完全一致。

英文摘要：

Based on the analysis of MapGIS water distribution system data and ArcGIS Geodatabase, a method of conversing MapGIS water distribution system data to the AreGIS platform is proposed. Through the unified processing of graphic data and attribute data and the rational setting of capture tolerance and elements level in the creating process of ArcGIS geometric network, this method makes the conversion of water distribution system data precise and quick. It＇ s proved that the ArcGIS water distribution system data conversed is accordance with MapGIS water distribution system well.
