Research on Automated Mapping Method for Tower Location of Overhead Transmission Lines
摘要
架空输电线路设计过程中
人工计算塔腿坐标与占地范围的shapefile(SHP)文件成图效率低、错误率高。针对这一问题
提出一种基于开源地理信息系统(geographic information system
GIS)库的自动化绘图方法
该方法不仅建立塔腿坐标计算的几何模型
还利用地理空间数据抽象库(geospatial data abstraction library
GDAL)/矢量数据处理库(OpenGIS Simple Features Reference Implementation
OGR)实现从杆塔参数到占地范围SHP文件的批量生成与可视化。西藏某500 kV线路工程的应用表明:该方法计算的塔腿坐标中误差为0.2 mm
实现了全流程、自动化塔位绘图
大幅提升了工作效率与数据准确性
而且软件安装便捷
具有良好的推广应用价值。
Abstract
During the design process of overhead transmission lines
manual calculation of tower leg coordinates and the generation of footprint Shapefile(SHP) files are inefficient and prone to errors. To address this issue
an automated mapping method based on open-source geographic information system (GIS) library is proposed
which not only establishes a geometric model for calculating tower leg coordinates but also utilizes the GDAL/OGR library to achieve batch generation and visualization from tower parameters to footprint SHP files. The application in a 500 kV transmission line project in Tibet demonstrates that the mean square error of the tower leg coordinates calculated by this method is 0.2 mm
which realizes the full process and automated tower position mapping
greatly improving work efficiency and data accuracy. Additionally
the software is easy to install and holds good promotion and application value.
