Integrity Of Data Collection And Computer Draw Of Urban Underground Pipelines

In order to make the management of the underground pipelines specialized and scientific, at the same time, lay a basis for the digital city, the general survey of underground pipelines in Huludao City is finished. It adopts the advanced computer and database technique and take into account the actual situation in Huludao City. It makes use of the technique of overall databases, which can entirely record the spatial 3D state of the underground pipeline network. It makes specific rules on the management of pipeline engineering after the general survey of underground pipelines, which is useful for the dynamic management of underground pipelines. This technique can create the resulting databases of pipelines, develop the data processing and rendering softwares of Plmap pipelines, and completely plot in computer. The overall design of databases and that of the data structure are advanced, which can entirely record the existing spatial states of underground pipeline network. This technique is created in the country at first.
