LiDAR (light detection and ranging), is a remote sensing technology that emits continuous laser pulses to calculate the position of objects in the surrounding environment.
LiDAR data is often collected by air, such as with this NOAA survey aircraft (right) over Bixby Bridge in Big Sur, Calif. Here, LiDAR data revelas a top-down (top left) and profile view of Bixby Bridge. NOAA scientists use LiDAR-generated products to examine both natural and manmade en...
LiDAR, which stands for “light detection and ranging”, uses laser light to measure distance and make highly accurate 3D maps and models.
What Is LiDAR? LiDAR is a remote sensing technology that measures distance using high powered lasers and light energy. To do this, LiDAR instruments target an object with a laser, measure the speed and intensity of the reflected signal, and then use this data to calculate the exact distance ...
LiDAR is a much more accurate technology, which makes it the ideal choice for many applications. It also has the ability to measure distance over time, which means it can create 3D models of objects and environments. However, there are some downsides to LiDAR, including its high cost and di...

Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at predictable wavelengths and growth rates. As dunes mature and coarsen, however, their growth trajectories become more idiosyncratic; nonlinear effects, sediment s
Other examples of how drone technology is used include the following: Agriculture.Drones measure and record the height of crops. They use lidar remote sensing technology that illuminates the crop with a laser and calculates distance by measuring what is reflected back. This can help farmersoptimize...
Convenience is an important part of our transformation. As customers change the way they use our forecourts, our sites will change with them. To connect more with our customers, we aim to: Increase our customer touchpoints from ~12 million a day in 2022 to >15 million by 2025 and to >...
The Elios 3, pictured below, has a modular payload equipped with a LiDAR sensor that creates 3D maps in real time.Although primarily used as an indoor inspection tool, the Elios 3's innovative technology makes it easier for inspectors to collect data and spot defects that need to be ...
