Transmission Line Mapping

The management of transmission corridors is complex and costly. Public utilities are under pressure to not only keep power flowing, but must also stay vigilant to maintain their infrastructure in compliance with regulatory agencies.

DroneTronik has mapped thousands of miles of transmission line, providing aerial mapping solutions that include ground topography, existing conditions in the right-of-way (ROW), vegetation baselines and encroachments, access road conditions, adjacent land use updates, and the detection of potentially hazardous trees outside the ROW. Aerial solutions are often far more efficient than on-the-ground surveys, quickly pinpointing areas where ground teams need to go in for a closer look.

We can capture every transmission tower, line and line hardware item along a 50-100 mile corridor in a single day. We can deliver LiDAR, photogrammetry, orthophotography and 3D oblique images, as well as PLS-CADD™ documentation. What you receive is a fully dimensioned 3D model of the ROW that depicts topography, vegetation, all structures, and all lines. Bring in our Enterprise GIS services and your management of this data is simplified. Couple this with an agreement to conduct annual reflights, and your cost savings improve yet again—compared to annual ground inspections.

Vegetation Management

Some outages are unforeseeable, and some can be prevented. The preventable outages are related to proactive corridor and line management. Keeping vegetation in check as well as keeping lines, towers, and hardware in good condition are the keystones of such a management program. Regulatory requirements and vegetation management place a cost burden on the power utility. A cost effective solution is to rely on aerial mapping and imagery services, supplemented by ground crews.

Deliverables

Our maps, aerial photographs, orthoimagery, thermal imagery and line profiles have multiple uses: They can (a) guide utility corridor maintenance crews, (b) assist engineering design teams with on-the-ground operations, and (c) be included with bid packages for potential contractors. The level of detail of each map will depend on the need. We can layer in ground contours, structural outlines, spot heights, street names, paths, boundaries, tax parcel information, and show natural features such as rivers and lakes. We can depict and annotate critical areas such as wetlands, buffer zones, and sensitive habitats.

Orthophotographs are scalable photographs, a valuable tool that enables transmission owners, engineers, and contractors to accurately measure distances on the images. When multiple data sets are required, we can multi-task—simultaneously collecting different data sets, such as LiDAR point clouds and visual imagery. The imagery can be oblique photography, digital pin-points, mosaicked orthophotos, infrared, or a video record. Data will be delivered in client requested formats, including in electronic and PDF hard copies.

Corridor Mapping for New & Upgraded Lines

Fixed wing aircraft collect approximately 40 linear miles of line per day, while flying at an altitude of 800 to 1200 feet. This platform is most suited to corridor planning, engineering design, and construction of new or upgraded lines, where the precision afforded by lower altitude flights is not required. Accuracies between 1 inche are typical. These deliverables support design iterations, allowing for designs to be checked against different criteria in PLS-CADD™ to identify the optimal route alignment, tower placement, and tower elevations.

Emergency Management

The pressure is on during and after a storm. Damage assessment and rapid power restoration is demanded. AeroMetric can support on the ground teams with rapid appraisal of line conditions, both high voltage backbone lines and low voltage pole-to-pole assessments. These can include damaged equipment, hazardous conditions, and downed tree assessments. In an emergency scenario, we can be airborne within hours of your call, capturing data to support power restoration teams, and thus limiting the potential for regulatory fines.

On-Going Support

When you engage DroneTronik for on-going services we will sit down with you to devise a complete solution for transmission line management. This can include the regular collection of data to support compliance and audits. We will capture data along your transmission rights-of-way, according to a pre-planned audit schedule. This will include capturing line and tower conditions, as well as clearances of vegetation and other hazards.

Before commencing services we will work with you to create a report format to best suit your requirements, meeting your own standards, as well as any national, state or local compliance that you might require. And we will then populate it with data after each monitoring cycle to keep your operations teams fully up-to-date. With AeroMetric’s technology at your side, you can stay in compliance and keep the power flowing.
