摘要
随着管线普查工作的开展以及管线基础数据库的建立,地下管线数据生命周期进入了"后管普"时代。城市地下管线被喻为城市的"生命线",如何保持这些"生命线"的生命长青,是"后管普"时代要解决的首要问题。由于管线属性的专业性以及管线探测外业技术的复杂性,采用传统的地形图更新方式——区域更新模式很难保证数据更新的统一性和实时性。本文根据实际工作,提出了一种要素级的实时更新模式和方法。
With the development of the pipeline census and the establishment of the pipeline database,the life cycle of the underground pipeline data processing has entered the era of"later-pipeline-census".Urban underground pipeline has been hailed as the"lifeline"of the city,and how to maintain the safety of the"lifeline"is the primary problem to be solved in the era of "later-pipeline-census".Because of the speciality of pipeline property and the complexity of pipeline detection technology,it is difficult to ensure the consistency and instantaneity of data updating by using traditional topographic map updating mode or regional update mode.According to actual working experience,this paper presents a real-time updating model and method of elements.
