Why is the Demand for LiDAR on the Rise?

Applied Tech Review | Tuesday, October 26, 2021

LiDAR is a flexible and accurate tool used to detect utilities under the ground surface.

Fremont, CA:Almost all industries are technologically advancing, and LiDAR is one of the essential tools being used today. LiDAR stands for light detection and ranging. It is a remote sensing tool that is used to detect utilities under the ground surface. LiDAR uses a unique GPS receiver, a Ground-Penetrating Radar (GPR) and a laser.

How LiDAR works

LiDAR generates detailed, 3D photographs of the contour of the Earth, its surface properties, and anything that might be present beneath, such as utilities, by combining light pulses with data collected by airborne systems. Typically, aeroplanes and helicopters are employed to collect data from LiDAR systems across a large geographic region; however, LiDAR can be used on various platforms.

There are two types of LIDAR. The first one is Topographic LiDAR, which uses infrared lasers to detect images. Second is Bathymetric LiDAR, which uses green light to penetrate into the water to look for things present under the water surface.

Advantages of LiDAR detection system:

Quick collection of accurate data

LiDAR is a technique for collecting a large amount of data in a short amount of time. Large data sets can be generated fairly rapidly due to the extensive geographic range of contemporary LiDAR devices.

High area density

LiDAR can develop detailed representations of items that are being surveyed even if they are beneath the surface because it is frequently utilized to penetrate the earth. This can be used to locate objects that would otherwise be hidden from view, such as utilities and flood plains.

Cut through vegetation

LiDAR is also capable of cutting through dense vegetation, such as forest canopies, allowing it to build accurate models when photogrammetry isn't possible.

Thorough flexibility

Alternatives mostly depend on light; however, LiDAR can be employed at any time of day or night. LiDAR is more useful than photogrammetry since it does not rely on ambient light sources because it emits light itself.


LiDAR can be used in conjunction with a wide range of other technologies. As a result, data processing can be automated, allowing experts to make decisions based on actionable data generated by a LiDAR system.
