Underground Pipe Network Data Calibration Method for 3D GIS Model Building
To effectively support the construction of 2D and 3D GIS models for pipelines,this paper focuses on the network"node edge"relationship and fully utilizes tools such as ArcGIS and Python to study the intelligent processing method for calibration of pipeline segment and pipeline point data.After practical application,the following conclusions have been drawn:the original 1117 pipeline units have been reorganized into 1306 pipeline segment units,and 189 new pipeline segments have been added;The number of pipeline point units has increased from 1148 to 1306,with 153 new nodes added.The processed pipeline data provides basic data support for pipeline 2D and 3D modeling and system construction,solves the problem of manual and labor-intensive calibration for unmarked nodes in pipeline data in existing technologies,realizes pipeline data calibration,and improves the accuracy of data processing.
