ITC Midwest says it will be conducting aerial LiDAR surveys of high-voltage transmission structures and lines throughout its Iowa and Minnesota service territory which includes the Dubuque are beginning today and continuing for approximately a week, weather permitting.
LiDAR stands for Light Detection and Ranging, which is a remote sensing method that uses light to measure distances from objects to the ground to create a three-dimensional data set.
The aerial surveys are conducted at low altitudes of 300 to 400 feet so officials say there is no cause for alarm if you see a low-flying helicopter near transmission lines while the survey is going on.
