What are the Top 5 Uses of LiDAR

LiDAR- Light detection and ranging. Though LiDAR is used in a number of applications, we have chosen Top 5 areas where LiDAR plays an important role.

Autonomous vehicles: 

If you’ve seen a self-driving car before, you’ve probably seen a LiDAR sensor. LiDAR works as an eye of the autonomous vehicle. Imagine if your eyes allowed you to see in all directions all the time. Imagine if, instead of guessing, you could always know the precise distance of objects in relation to you.

LiDAR enables a self-driving car to view the surroundings with special powers.


LiDAR can be used to create 3D elevation map of a particular land.  This can be converted to create slope and sunlight exposure area map.

This information can be used to identify the areas which require more water or fertilizer and help the farmers to save on their cost of labor, time and money.

What is LiDAR and how does it work?

River Survey: 

Water penetrating green light of the LiDAR can be used to see things underwater and helps create a 3D model of the terrain. Underwater information of a river can help understand the depth, width, and flow of the water. It helps in monitoring the floodplains.

Modelling Pollution:

LiDAR wavelength is shorter. It operates in ultraviolet, visible region or near infrared. This helps to image the matter which is of the same size or larger than the wavelength. So LiDAR can detect pollutant particles of carbon dioxide, Sulphur dioxide, and methane. This information helps researchers to create pollutant density map of the area which can be used for better planning of the city.

Archeology and Building Construction 

LiDAR plays an important role for the archeologist to understand the surface. LiDAR can detect micro-topography that is hidden by vegetation which helps archeologist to understand the surface.

Ground-based LiDAR technology can be used to capture the structure of the building. This digital information can be used for 3D mapping on the ground which can be used to create models of the structure.  It is very useful for maintaining a record of the structure.
