Project Spotlight: Electric Utility Mapping + Inspection

130 Miles of LiDAR Mapping

Description of Work: Airborne LiDAR data collection capturing overhead electric conductors and supporting structures

Project Specs/Limits: total of 130 miles - 300-foot-wide corridor, 150 feet left and right of the centerline of the crossing overhead electric conductors and supporting structures crossing perpendicular to the main traveled portion of each major highway along with the connected two spans and supporting structures on either side of the highway, which constituted 5 spans of wire and six poles per crossing. There were 109 crossings.

All mapping utilized the client feature codes.

Weather data was acquired during LiDAR data acquisition.

High resolution oblique imagery of the individual transmission line runs.

Geo-referenced digital RGB, high resolution images of the transmission structures.

Deliverables included:

Power Line Systems (PLS-Cadd) file(s) containing all feature coded survey data

Planimetric mapping (.DGN and .DXF)

Digital Orthophotography – 3 inch pixel (.TIF/.ECW)

LiDAR Accuracy reports

Weather data at the time of mapping
