Lidar technology
Airborne lidar technology is widely accepted among power utility companies as an efficient tool for acquiring geo-referenced spatial data for various applications essential to power line asset management.
New route design can take the fundamental advantages of the lidar workflow which is all-digital format of its data collection, processing, analysis, delivery, and storage steps. By integrating high accuracy point cloud data and imageries with powerline GIS software workflow, it optimizes the route selection, tower construction site, cross section, data transfer, it realizes a seamless work flow from survey , designing, construction to transfer the asset to operation management. This maximizes the efficiency of the entire workflow, effectively avoiding duplication, saving investment. Furthermore, digital data acquired during an initial lidar survey can be archived and used to form the foundation of a permanently searchable and editable database, allowing subsequent time-based studies such as change detection.
As built powerline can use airborne LiDAR to modeling of existing routes and infrastructure, achieve a three-dimensional reconstruction of powerline corridor, recovery powerline corridor geospatial data, surface attachments (trees, buildings, etc.), the line sag, the position and the tower model, supplemented by powerline facilities and equipment parameters to achieve full digital line corridor asset management and visualization . It is often used in eengineering analysis/calculations for maintenance and upgrade, e.g. tower positions, sag analysis, thermal up-rate, load modeling, clearance and critical distances.
New Route Planning and Line Construction
Airborne LiDAR technology can provide users with a resolution better than 0.1 meters orthophotos, digital elevation model , cross section and contour. Surface features can be visualized, vertical and horizontal spatial information can be obtained in office computer from the chart, the designer in the office has all the feature which can viewed across computer for project design, including crops along the corridor private land boundary, houses etc..
Line Optimization and Line Construction
The site selection involves quite a lot factors, it is one of the most difficult process of transmission design. Airborne LiDAR system provides high-precision, high-resolution orthophoto (DOM), a digital elevation model (DEM) and laser point cloud data, LiDAR point cloud was loaded into professional software platform to optimize route selection and tower site selection. Through the unique spatial data processing engine, LiDAR data was compressed, stored, classified, indexed. It make the data can be fast read or searched. In the mean time, combined with two-dimensional map, a cross section view of a variety of three-dimensional map perspective, the real 3D corridor are compacted into designer’s office, which allows designers to "look around", "take into consideration of high or low stakes", consider the terrain, social factors , and ecological environment to optimize the design..
All Digital Information Exchange
Airborne lidar technology is a powerful tool to maximize the efficiency of power line design and asset management. It represents a clear advance over traditional surveying methods for power line applications because it provides several key advantages like unprecedented data collection efficiency, an all-digital workflow and excellent data quality and accuracy. It creates a digital platform among powerline designing institutes, constructions contractor and operation companies. It realized a seamless handover the digital data on demand among the three parties. Therefore, airborne lidar data is highly suitable for reliable engineering design and analysis of the physical parameters of power lines, and for the management of powerline construction and maintenance.
