LiDAR (Light Detection and Ranging) is an airborne laser system that is used to acquire X, Y and Z coordinates of the earth's terrain surface and other surface features that are both natural and manmade. Most often, LiDAR data is processed to create Bare Earth DEMs that are used to generate surface models from which accurate topographic contours can be generated and/or to serve as surfaces to which aerial images can be differentially rectified to create digital orthophotos. Other LiDAR data models include tree canopy definition, volumetrics, airfield obstruction studies and others.

How it Works
The Atlantic Group uses the OPTECH 3100 LiDAR Mapping Systems to collect surface elevation data that is processed to create various LiDAR-based model data sets. Our Optech 3100 is mounted in our Cessna 210 aircraft.
LiDAR can produce detailed information of power utility infrastructure to provide answers for engineering questions in line management, design and maintenance needs.
• 100,000 pulses emitted per second - 3 to 4 points per foot on line
• Allows for identification of attachment points and catenary for each Transmission Circuit and Shield Wire
• Conductor-to-ground & conductor-to-conductor accuracy to 1 cm
• Identification of lines or wires crossing the Transmission line
"Increasingly, aerial LiDAR imaging surveys are recognized as the ideal data source to build models for engineering analysis because their full capabilities, functionality and effectiveness are greatly affected by the quality and accuracy of the data used. With high-density, high-accuracy and abundance of LiDAR measurement points, a Transmission Engineering Model (TEM) can provide even better perspectives using contour lines, color renderings, draped aerial photographs, LiDAR data and superposition of planimetric maps used to better visualize the area around the line."
