Data processing method and system for CAD urban pipeline as-built drawing based on ArcGIS platform

Abstract

The invention discloses a data processing method and system for a CAD urban pipeline as-built drawing based on an ArcGIS platform. The method comprises the following steps of loading data of the CAD urban pipeline as-built drawing; setting layer import configuration, wherein the corresponding relation between the data of the CAD urban pipeline as-built drawing and layers of a target pipeline space database is set; guiding the data of the urban pipeline as-built drawing into the target pipeline space database according to the layer import configuration, building a geometric network through the ArcGIS in the guided target pipeline space database, associating attribute assignments for pipelines and pipe points in the urban pipeline space database through a geometric network development interface provided with an ArcGIS Engine according to the built geometric network, guiding an associated pipeline table and an associated pipe table out, and reforming a drawing by the utilization of the associated attributes of the urban pipelines and the pipe points. By the utilization of the ArcGIS geometric network technology, various problems in the process of processing the data of the urban pipeline as-built drawing are automatically solved, a large amount of manual operation is avoided, and the error rate is reduced.

Description

technical field [0001] The invention relates to a data processing method and system for a CAD urban pipeline as-built drawing based on an ArcGIS platform. Background technique [0002] The common format of urban pipeline as-built drawing is CAD file. Here, taking CAD file processing as ArcGIS data format as an example, an optimized processing method for urban pipeline as-built drawing is proposed. [0003] Analysis Common CAD files usually contain multiple layers. When loaded into ArcGIS, each CAD layer will correspond to three layers of points, lines, and planes in ArcGIS format, and then the urban pipeline completion data will be imported into the city In the spatial database of the pipeline, the imported data is finally corrected and adjusted according to the actual situation. However, in practice, the last step of data correction may often be the part with the largest workload, which is also the solution scope of the present invention. [0004] Assume that the pipeline...

AI Technical Summary

Problems solved by technology

[0031] 1. Frequent query processing is required;

[0032] 2. It needs to be controlled to extend each pipeline to the position of the pipe point, and the operation is cumbersome;

[0033] 3. Unable to associate the attribute connection relationship between pipe points and pipelines

That is: in the urban pipeline, there is a connection relationship on the attribute, and the number of the pipe point corresponds to the starting point number and the ending point number of the pipeline. The traditional method cannot do this

[0034] 4. Large error and high error rate
