Geiger-mode LiDAR - Utility and Power Solutions
Transform utility management into a science with high-resolution LiDAR point cloud data.
Geiger-mode LiDAR data is more precise and uniform, providing greater detail to extract pole and wire assets down to distribution level detail. Since data are collected as wide-area coverages, other critical information can be obtained in contrast to typical right-of-way-only collection approaches. This unique technology creates point clouds that support derivative products for a variety of utility applications and subsequent analytics across all parts of the organization.
High-resolution Calibrated Point Clouds
Typical point density range for utilities projects are from 20-30 points per square meter, however, different point densities can be processed at the customer’s request. The base level product consists of an unclassified (non-attributed) point cloud, which is calibrated to meet a specified accuracy, can be processed into numerous downstream products such as asset extraction (wires, poles, others), vegetation encroachment, as-built drawings, or other analyses.
Utility Classified Point Clouds
Utility classification schemes vary by customer and point attribution can be customized to customer specifications. Typical classification schemes include a minimum of ground, vegetation, man-made features, poles, and wires. These can be further evolved to other assets or land cover stratifications such as height, density, or type. Uses for this product include asset extraction of wires, poles, and others for as-built GIS mapping and updates, vegetation encroachment, PLSCAD, or other analysis.
Vegetation Encroachment Analysis
Vegetation encroachment analysis is performed by extracting 3D vectors of wire and pole assets to determine the distance to right-of-way vegetation and other man-made hazards. Data can be used to perform tree-clearing operations, improve the reliability of the network, and optimize logistics for remediation tasks.
Multiple clearance analysis can be performed based on voltage and cutting methods to create project plans. Typical analysis of transmission includes sag (ground/vegetation to conductor), sway (blowout condition vegetation/manmade hazard to conductor), or fall-in (outside the right-of-way) detection based analysis. For distribution, several options including cutting method analytics (side/cored/removal) can be performed. Uses include GIS database of 3D as-built assets, project planning, encroachment remediation, and audit reporting.
Advanced Analytics for O&M Planning and Remediation
After vegetation encroachment analysis is performed, data can be created for easy office and field systems in a simple deployable format to show specific vegetation areas for remediation based on any customer criteria, such as coring, side cutting, or removal.
The Harris analytics platform can create any number of criteria, including prescriptive treatment plans based on the height and vegetation density, to better understand the most cost-effective approach, such as herbicides, brush hog, chainsaw, bucket truck. Multiple clearance analyses can be performed based on KVA and cutting methods to create project plans. Uses include prescriptive vegetation encroachment budget planning, logistics, and remediation.
