Booming Applications of LiDAR Technology

In the last decade, technological advancements in the field of light imaging have been massive. The LiDAR technology is witnessing exponential growth in the application and uses as it has provided a breakthrough in cutting down human dependency and cost in various sectors. Carrying out procedures has become feasible and continues to cover more and more grounds due to its promising nature.

What is lidar?

The term lidar is an abbreviation for light detection and ranging or laser imaging, detection, and ranging. It is a technique for determining ranges of varying distances involving a laser to target any substance or thing and measuring the time it takes for the reflected light to return to the receiver. It is also known as 3-D laser scanning, which is a hybrid of 3-D scanning and laser scanning.

Due to variances in laser return durations and changing laser wavelengths, light detection and ranging technology may also be used to create computerized 3-D renderings of places on the Earth’s surface and ocean bottom. It has been used on the ground, in the air, and on mobile devices.

How does it work?

Using light in the form of a pulsed laser, light detection and ranging measures ranges (changing distances) to the Earth. Exact three-dimensional information on the Earth’s structure and surface features is obtained when these light pulses are combined with additional data collected by the aerial system.

Light detection and ranging instruments comprise three parts: a laser, a scanner, and a specialized GPS receiver. The most frequent platforms for collecting data over large areas are planes and helicopters. Topographic and water depth measuring devices are the two forms of light detection and ranging.

Water depth light detection and ranging systems employ water-penetrating green light to determine seafloor and riverbed elevations. In contrast, topographic light detection and ranging use a near-infrared laser to scan the land.

Scientists and mapping experts can use these technology devices to analyze natural and man-made surroundings with accuracy, precision, and flexibility. NOAA scientists are using light detection and ranging to create more accurate coastal maps, create digital models of altitude plains for use in geographic information systems, and assist in emergency response operations, among other things.

Booming Applications

A significant adaptation of light detection and ranging has been in using drones in conjunction with laser scanners and other remote sensors to scan smaller regions at a lower cost. Drone remote sensing also avoids any hazard that staffed aircraft personnel face in challenging terrain or distant locations. Here are more applications of light detection and ranging systems that have brought ease and cost-reduction, making drone use more feasible.

Land surveying

Drones using these sensors can generate 3D digital terrain models (DTM) of remote or rugged locations rapidly, accurately, and cost-effectively. When a manned aircraft is a costly affair and a threat to the life of the personnel, Drones are the ideal instrument for covering specified land areas. Drones are less expensive and quicker to deploy than planes or helicopters, lowering costs and risks.

Power Maintenance

Power line maintenance poses a significant safety risk. Power line faults can be detected using light detection and ranging technology before they become a problem. Utility firms can swiftly assess the damage and create a solution with the slightest danger by using drones.

Forestry and Agriculture

Drones outfitted with light detection and ranging systems can examine vast farms and evaluate how resources might be utilized to boost productivity. These can also be used to construct 3D models of the area of human activity on forest lands. Light detection and ranging systems have the advantage of being able to penetrate tree cover.

Mining

Light detection and ranging have shown to be a valuable tool for determining material volumes in open-pit mines without affecting on-the-ground operations. Drones are being integrated into mining workflows to save time, money, and risk exposure.

Transportation

Light detection and ranging technology is an excellent tool for city planners aiming to expand mass transit systems and rail stations. UAVs equipped with light detection and ranging sensors can scan large areas and collect data that can be used to help plan future transportation projects.

Landslides

Prior to the widespread use of light detection and ranging, geologists cataloged landslides using aerial pictures, topographic maps, and field surveys. Because of the dense foliage in Washington, this strategy is challenging to apply because it often obscures details or makes field checking difficult. Landslides frequently have distinct topography that is noticeable once it is discovered. A landslide can be identified by slump blocks, hummocky topography, scarps, and sag ponds. A geologist can use light detection and ranging to search large land areas for landslides faster and more precisely than using aerial pictures alone.

Management of Flood Risk

Light detection and ranging can be used in a variety of hydrologic applications. Floodplains can be meticulously mapped. Flooding models can be constructed to demonstrate which areas are at risk. Abandoned channels, ditches, terraces, and levees can all be identified as subtle river features. This enables land managers and decision-makers to manage flood zones better, retain natural floodplain functions, and create emergency response methods.

Navigation

Light detection and the ranging system are now being employed in self-driving vehicles. Lasers are used to measure distance and speed for all nearby objects, allowing the car’s computer to map the environment in real-time. This enables adaptive rates concerning oncoming traffic, adaptive suspension, and automatic parking.

Aerial robots can also utilize Light detection and ranging systems to map the terrain underneath them. By measuring the robot’s speed and location concerning its surroundings, they can safely avoid obstacles and land. The software can classify items it discovers using Light detection and ranging system data, allowing military robots to identify targets.

Conclusion

Light detection and ranging systems are widely utilized in surveying, geomatics, archaeology, geography, geology, seismology, forestry, and military operations. The introduction of lidar systems has revolutionized critical operations, making them safer for humans. This has opened up avenues where high-risk tasks can be possible, like detecting and studying volcanic eruptions, making way for new opportunities in the near future.
