摘要
为有效支撑管线二三维GIS模型的构建,本文基于网络“节点-边”关系,充分发挥ArcGIS、Python等工具的作用,研究了管线段与管线点数据校准智能化处理方法。经过实践应用得出以下结论:原1117条管线单元被重新划分成1306个管线段单元,新增189条管线段;管线点单元由原来的1148个增加到1306个,新增153个节点。经处理后的管线数据为管线二三维建模及系统构建提供了基本的数据支撑,解决了现有技术针对管线数据部分节点未被标记的情况进行人工逐条校准费时费力的问题,实现了管线数据的校准,提高了数据处理的精确度。
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.
