UAS LiDAR Transmission Line River Crossing

CEC was tasked with acquiring aerial LiDAR data for a section of 138kV transmission line where CEC’s Transmission Department was designing a new long, overhead crossing spanning the Canadian River.

The long River Crossing allowed CEC to leverage its LiDAR-equipped UAS platform to acquire the needed 3D laser scan data. Utilizing a rotorcraft UAS, the data was acquired “low and slow” in order to capture a high point density. CEC’s flight team planned and performed the flight safely and efficiently with a total time on site at less than an hour.

The acquired data was post-processed and classified. The 3D laser scan data was used to generate a highly detailed topographic model in PLS-CADD where CEC’s Transmission Department designed the new crossing and modeled line sag.
