【摘要】 城市地下管线数据动态更新相较于管线普查工作,具有长期性、复杂性、现势性等特点,本文结合实际案例,主要讨论了对城市公共域内的新建管线、变化管线外业巡查、现场核实和补测,并经数据编辑质检后入管线数据库的几种方法的可行性,介绍了在管线数据更新实际工作中发现的几种典型情况的处理方法和思路,希望通过以上作业方式,尽可能节约外业巡查时间,提高动态更新工作质量,从而达到"现场巡查,现场探查,现场测量,快速成图更新"的目的,使城市地下管线动态更新维护工作能够达到快速测绘、快速应用的目的。更多还原

【Abstract】 It has the characteristics of long-term,complexity and current etc for dynamic updating of urban underground pipeline data compared to the pipeline general survey work. With actual cases,the paper discussed the feasibility of several methods about new pipeline in urban public area,external inspection of changed pipeline,field verification and survey,data storing after data editing and quality inspection. Meanwhile the paper introduced the treatment methods and ideas of several typical cases found in the actual work of pipeline data updating. Through the above operation mode,we hope to save the inspection time of external inspection as far as possible and improve the quality of dynamic updating work to achieve the purpose of on-site inspection,field exploration,field measurement,and rapid mapping. Realizing the purposes of rapid mapping and rapid application in dynamic updating and maintenance of urban underground pipeline.更多还原
