MAPGIS 3D pipeline modeling awakens the pulse of urban underground pipelines

Underground pipelines are an important part of urban infrastructure , Is to ensure urban production 、 An important basic condition for the normal operation of life , It's the city's “ Lifeline ” and “ Blood lineage ”. With the rapid development of urbanization in China , The spatial distribution of underground pipelines is becoming more and more complex , The original two-dimensional graphics technology has been unable to meet the needs of showing the complex spatial distribution and relationship of underground pipelines , In particular, it is more difficult to express the distribution of longitudinal pipelines in underground space .

Three dimensional pipeline has unique advantages in dealing with the shortcomings of the two-dimensional pipeline management mode mentioned above . Through three-dimensional visualization of pipeline data , The buried pipelines are displayed to users in the form of three-dimensional models , Users can have an intuitive understanding of the complex spatial distribution between pipelines .

In the investigation of urban underground pipe network , Types of various complex pipe networks 、 The route direction is clearly displayed on the computer screen through three-dimensional imaging , The staff can use the three-dimensional realistic three-dimensional pipeline model , Intuitively understand the distribution of pipelines in each region from different directions , Conveniently obtain the plane position and burial depth of underground pipelines 、 trend 、 Connection relationship and other information , This is based on MapGIS Application scenario of 3D pipeline modeling tool , Hidden underground pipeline information “ move ” Come out and visualize , Empowering urban pipe network construction management .

adopt MapGIS 3D pipeline modeling tool , The user can , Quickly generate 3D pipeline model , It saves the tedious work of manual modeling and splicing pipe segment model ; and , Generated 3D pipeline model , You can see the three-dimensional spatial information of the pipeline model , You can also see various attribute parameter information of the pipeline model . Through the pipeline 3D modeling tool , Just make sure to provide standardized two-dimensional pipeline data , You can mass produce 3D pipeline models .
