LiDAR 101: 5 LiDAR Technology Applications You Need To Know

September 12, 2021

LiDAR, for most people, this word may sound unfamiliar. LiDAR is a remote sensing and surveying technique used to measure the distance and dimensions of landscapes and structures with laser scanners.

It transmits light pulses to objects like buildings, roads, and landscapes. LiDAR measures how long it would take for the light waves to bounce off the surface and return to the system. LiDAR technology has become a necessary tool in different fields. Light Detection and Ranging is no longer a specialized technique only used by specialists.

Through innovative projects such as self-driving cars and innovating the agricultural sector, it is transforming urban planning processes and has developed itself as a leading technology. With LiDAR technology growing in popularity, now is an excellent opportunity to learn more about it and its practical applications in different areas.


Agriculture technology (AgTech) businesses can use LiDAR to find places with excellent sunlight for more effective production of crops. Researchers can use LiDAR to create a topological map of the fields. LiDAR technology can also train machine learning systems to locate crops requiring water or fertilizer.

If you are interested in knowing the LiDAR vegetation solutions that you could use to understand how you could increase production, you might want to do some background research about it. Nevertheless, LiDAR technology in the agricultural sector helps many farmers reduce labor costs, time, and money.

Farmers may also use LiDAR technology to find out information about the soil type of a specific piece of farmland. This information is helpful since it advises them about the crops produced on the land and the suitable fertilizer.

Land segmentation is another essential application of LiDAR in agriculture. Experts have evaluated the data using LiDAR technology to highlight land patterns and use the information to divide the land for multiple uses.

River Surveying and Oceanography

Specialists can use LiDAR’s water-penetrating green light to see elements underwater and aid in creating a 3D model of the terrain. A river’s underwater information can help determine the depth, width, and flow of the water. It aids in floodplain monitoring.

LiDAR technology is also used by authorities when they need to know the exact depth of the ocean’s surface to find any object in the event of a maritime incident or for research purposes. Apart from spotting items, LiDAR is also used to calculate phytoplankton fluorescence and biomass at the ocean surface.


LiDAR technology is a great tool for city planners aiming to expand mass transit systems and rail stations. UAVs or crewless aerial vehicles such as drones equipped with LiDAR sensors can scan large areas and collect data that planners can use to help plan future transportation projects. The technology measures the exact location to assess the road condition.

LiDAR systems present comprehensive geographic information as a 3D virtual world that professionals can view from varied angles. The dataset can be used as a 3D model to link various other data, such as traffic and crash data.

Land Surveying

Land management organizations can monitor land resources in real-time, allowing faster and more efficient mapping than aerial surveys. They also utilize it in disaster planning, early warning systems, an emergency response such as forest fires, and location-based examinations.

Absolute location accuracy is provided by LiDAR mapping. This allows viewers to see where LiDAR collected the data worldwide and how each point relates to items in terms of distance.

Surveyors can use the data from LiDAR point clouds to map entire cities. In perfect precision, decision-makers can target structures or areas of interest. Land surveying is usually quite important in the building process.

This is because any facility that needs to be built must have its land examined before construction. LiDAR systems provide a variety of utilities or capacities for analyzing all physical aspects of the area. As a result, LIDAR allows for more efficient surveying and land analysis, which is helpful to construction.


LiDAR is a technology that allows vehicles of various types to determine whether hazards are close and how far away they are. LiDAR components provide 3D maps that can detect the position objects and identify what they are. LiDAR data also assists a vehicle’s computer system notice how things will behave and adjust the vehicle’s navigation accordingly.

You’ve probably seen a LiDAR sensor before if you’ve seen a self-driving car. LiDAR serves as the vehicle’s eye. It gives users a complete 360-degree picture of their surroundings, allowing them to drive securely.

Autonomous vehicles use LiDAR to detect and avoid hazards ahead of them, allowing them to smoothly and prevent crashes. This technology enhances commuter safety and makes self-driving cars less likely to cause accidents.


LiDAR, a pulsed laser technology, has many mapping applications and gives detailed information and environmental data that help many sectors. It is one of the reasons why the world is developing and striving. To truly appreciate the advantages and applications of LiDAR technology, you must first understand how it works.
