The urban underground pipeline mainly comprises pipelines such as water supply, rainwater, sewage, fuel gas and the like, auxiliary facilities and the like. Pipeline data is the basis for pipeline analysis, visualization applications, and the like. Urban underground pipe networks can be abstracted into a mathematical model of pipeline point-pipeline segment, and the prior art mainly adopts a data structure of two points and one line. The pipeline vector data is composed of a line with pipeline segment attribute and coordinate information and node data with pipeline point attribute information and coordinate information. For two-dimensional vector data of urban underground pipeline parts, key break points are not marked, namely, when pipeline segments are divided, a plurality of continuous directed lines are divided into one pipeline segment, and meanwhile, when pipeline data are newly added to a pipeline network, the original pipeline data need to be updated according to the newly added pipeline data. In the prior art, aiming at the problem that some nodes of pipeline data are not marked, unmarked points are usually directly ignored, or calibration is performed manually line by line.
