Mitigating Risk and Prioritizing Work for Distribution Vegetation Management with Lidar Analysis

From Ground Patrols to Geospatial Intelligence: A New Approach to Distribution Vegetation Management 

For electric utilities, vegetation management has always required balancing risk, resources and the realities of the terrain. In heavily forested or difficult-to-access service territories, that challenge becomes even greater. Utilities need to inspect thousands of spans, identify vegetation that could threaten electrical infrastructure and prioritize work, all while managing limited field resources and increasing expectations around wildfire mitigation and system reliability. 

Traditionally, much of that work has depended on ground patrols, with arborists walking distribution lines to identify clearance issues and potentially hazardous trees. That expertise remains essential. But through our work with utilities, NV5 has seen how aerial lidar and geospatial analytics can change where and how that expertise is applied. 

Rather than sending skilled personnel across an entire network to search for potential problems, utilities can use lidar to build a detailed view of conductors and surrounding vegetation, apply analytics to identify areas of concern, and then direct field teams to the locations where their judgment is most valuable. 

Seeing Vegetation Risk Across the Network 

A modern lidar-based vegetation management program begins with accurate, high-density data. NV5 brings decades of remote sensing experience and deep expertise in aerial lidar acquisition, processing and analytics to help utilities create that foundation at network scale. 

Aerial lidar can capture the three-dimensional relationship between electrical infrastructure and surrounding vegetation, including conductors that may be difficult to assess consistently from the ground. From that foundation, geospatial analytics can identify several types of vegetation risk, including: 

• Grow-in: Vegetation growing into required conductor clearance areas 

• Fall-in: Trees capable of striking electrical infrastructure if they fail 

• Overhang: Vegetation extending above or across conductors 

Analytics can also provide information such as tree height, crown geometry and lean direction. By combining those insights with proximal data, utilities can move beyond simply identifying vegetation near a line and begin evaluating which conditions warrant attention first. 

From Finding Problems to Prioritizing Risk 

That distinction is important. The goal of vegetation management isn’t simply to create a list of every tree near electrical infrastructure. Utilities need to understand where conditions present the greatest potential risk and determine how best to deploy available resources. 

This is where NV5’s combination of remote sensing, utility domain expertise and advanced geospatial analytics becomes particularly valuable. Geospatial analytics can help model conductor position and sag, evaluate tree height and distance, identify fall-in potential and incorporate additional information such as fire-risk areas. Other datasets, including satellite-derived vegetation health information, can add another dimension by helping identify stressed or declining trees. 

Together, these capabilities shift the question from “Where is vegetation close to our lines?” to “Where should we act first?” 

Making Field Expertise More Valuable 

Lidar doesn’t eliminate the need for arborists or other vegetation management professionals. It changes how their time can be used. Instead of spending much of an inspection cycle searching for potential hazards across miles of distribution lines, field teams can be directed toward locations where data has already identified a potential concern. They can then validate conditions, determine the appropriate response and apply the contextual judgment that geospatial data alone cannot provide. 

For utilities managing large networks, this creates an opportunity to increase inspection capacity without attempting to achieve the same gains solely by adding field personnel. NV5’s approach is designed to complement that field expertise, using technology to focus skilled resources where they can provide the most value. 

Building a Repeatable Vegetation Intelligence Program 

The value of lidar also grows when utilities move beyond one-time acquisition. Consistent data collection and analysis can provide a repeatable foundation for understanding vegetation conditions across the network over time. Instead of treating each inspection as an isolated snapshot, utilities can build a more continuous picture of changing conditions and emerging risks. 

That requires more than collecting a point cloud. A successful program depends on consistent acquisition, appropriate point density and accuracy, repeatable processing, network modeling, vegetation analytics and integration with the systems utilities use to manage their work. 

NV5 supports that full lifecycle, from data acquisition and processing through analytics and integration, helping utilities turn large volumes of geospatial data into information that can be incorporated into operational workflows. The objective is not simply better data. It is turning that data into information that can support action. 

Start with the Operational Question 

For utilities considering lidar-based vegetation management, the best starting point may also be the simplest: identify the operational question you need to answer. At NV5, that’s where we believe the conversation should begin, not with a particular sensor or technology, but with the operational challenge the utility is trying to solve. 

That might begin with measuring vegetation clearance around conductors. Once the lidar foundation is established, additional analytics and datasets can be incorporated as operational needs evolve, from identifying fall-in hazards and monitoring vegetation health to supporting broader wildfire mitigation initiatives. 

The technology can become increasingly sophisticated, but the measure of success remains straightforward: Does it help the utility identify risk sooner, prioritize work more effectively and put skilled people where they can have the greatest impact? 

With expertise spanning remote sensing, lidar, utility infrastructure and advanced geospatial analytics, NV5 helps utilities connect these capabilities into practical vegetation management programs. By combining aerial lidar, geospatial analytics and field expertise, utilities can move vegetation management toward a more proactive, intelligence-driven model, one designed not simply to collect information, but to turn that information into action.
