"The Terrestrial Light Detection and Ranging (LiDAR) System Market is expected to grow at a CAGR of 11.7% by 2030, driven by the increasing demand for accurate and high-resolution spatial data.”

About LiDAR:

Lidar, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth.

It is a technology that measures the distance to an object by scanning a laser over the object and detecting the reflected light with an optical sensor.

These light pulses—combined with other data recorded by the airborne system — generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.

A lidar instrument principally consists of a laser, a scanner, and a specialized GPS receiver. Airplanes and helicopters are the most used platforms for acquiring lidar data over broad areas.

Two types of lidar are topographic and bathymetric. Topographic lidar typically uses a near-infrared laser to map the land, while bathymetric lidar uses water-penetrating green light to also measure seafloor and riverbed elevations.

Lidar systems allow scientists and mapping professionals to examine both natural and manmade environments with accuracy, precision, and flexibility.
