摘　　要：管道工程在勘察、设计和施工期间产生大量的地理信息数据,它们多数以关系数据的形式呈现。文章借鉴APDM的线性参考技术,论述了建立管道中心线模型和使用线性参考技术将关系数据转化为几何要素的方法。三维可视化一方面解决了普通关系数据表达能力差、缺少空间概念的劣势;同时也消除了普通关系数据对中心线的依赖,避免了因为线路调整后造成的歧义。文章论述内容对管道勘察、设计和施工期管道中心线经常发生优化背景下,地理信息的生产和管理有着很好的推广应用价值。Large quantity of GIS data are made in Pipeline engineering and construction phases.Most of them are presented in relational data.Based on the Linear Reference technology of APDM,this paper discusses the establishment of pipeline centerline model and linear reference method;And a method of converting relational data into geometric features.On the one hand,3D visualization solves the disadvantage of poor expression ability of common relational data and lack of spatial concept;meanwhile,it also eliminates the dependence of relational data on the centerline and avoids ambiguity caused by route optimization.The content discussed in this paper has a very good value of application to the production and management of geographic information under the background of frequent route optimization in pipeline survey,design and construction phases.
