摘　　要：排水管网属于地下隐蔽设施,具有变化慢、变化隐蔽两大特点,因此其空间数据主体相对稳定,而改造节点、更新数据困难。本文通过排水管网GIS系统收集管网管理一线工作人员存在的数据问题,针对这些问题进行修补测及成果确认,从而快速修复管线,完善排水管网数据库,提高数据现势性。The drainage pipe network is an underground concealed facility that with slow change and change hidden two characteris-tics, which makes the main body of spatial data is relatively stable and the transformation of nodes and update the data difficult. Col-lecting the data of the frontline staff in the network management through GIS system of drainage pipe network for repair measurementand result validation for these problems, in order to quickly repair the pipeline data, perfect the drainage network database and im-prove the present situation of data.
