摘要
城市地下管线GIS数据库建成后,即面临数据应用-更新-维护-应用的反复循环的问题,特别是在城市快速建设与发展时期尤其如此,本文就昆明市滇池治理重点工程-城市地下雨污分流改造为代表,针对过程中对地下排水管线GIS数据的使用,尤其针对数据需求、数据采集、数据更新过程及地下管线GIS数据库工作方式设计与运行,提出大工程背景下解决地下管线信息更新存在问题的若干技术方法。
When underground Pipeline GIS database is completed,it will face data applications-Update-maintenance-the application of repeated cycles,especially in the period of the rapid construction and development of the city,In this paper,key projects for the Dianchi Lake in Kunming-the city to transform the process of diverting rain pollution of underground drainage lines to use GIS data,especially for data needs,data collection,data updating process,and Underground Pipeline GIS database design and operation work,made a number of technology solutions to large underground pipeline engineering background update problem.
