摘　　要：随着地下市政基础设施普查的全面开展,涌现出标准各异的海量地下管线普查数据。为提高管线普查数据的处理效率与利用率,基于国产化GIS平台,以浙江省地下市政基础设施数据库规范为例,提出一种地下管网三维模型的自动化构建与可视化方法。该方法在数据规范性检查与自动修正的基础上,完成三维拓扑构网;然后制定符号化规范,实现了三维管网的自动符号化。实现了从符合特定规范的管线测绘数据到模型化三维拓扑管网的全自动化处理,为大批量的规范化管线测绘数据的高效处理提供了一个解决方案。With the development of underground municipal infrastructure survey,a large amount of underground pipeline survey data with different standards emerged.In order to improve the efficiency and utilization of pipeline survey data,based on the domestic GIS platform,taking the specification of Zhejiang underground municipal infrastructure database as an example,a method of automatic construction and visualization of 3D models of underground pipe network was proposed.Based on the data normalization inspection and automatic correction,the method completed the 3D topology networking,and then formulated the symbolization specification to realize the automatic symbolization of 3D pipeline network.It realized the automatic processing from the pipeline surveying data compliance with predefined specification to the modelling 3D topology pipeline network and provided a solution for the efficient processing of large quantities of standardized pipeline surveying data.
