LiDAR is Changing Mapping and Geospatial Data: What To Know

3D mapping helps depict objects in great detail, whether it is a building or object on the earth. The advances in 3D mapping technology has turned these complicated tasks into efficient processes. The ability to gather data at a high rate with top accuracy saves time and improves quality of data collected. 

There is a huge focus on using drones with high-quality sensors and cameras to produce high resolution data for a multitude of industries. LiDAR or light detection and ranging is a remote sensing method that can help map out highly vegetated areas.

LiDAR can be used to create detailed digital landscapes, terrain, and even elevation models. These are used for various applications in business that span a number of industries. Below are a few types of situations LiDAR and drones can help with. 

Construction Planning

LiDAR is a game-changer for land developers, as they need to have a deep understanding of the site and the topography of the land. Using LiDAR technology a very detailed map of an area can be created, even if there is a lot of vegetation. Once construction is underway progress monitoring can be done using drones to quickly identify areas that could be more efficient, as well as how on track the project is to completion.


Assessing large areas of forest is important for many different industries. Managing large areas in the traditional manner is extremely difficult due to the immense acreage and landscape of these forests. LiDAR equipped drones are able to collect data on the area, so licensed professionals can make informed decisions. Because of the rate at which the LiDAR sensor pulses out laser beams, it is able to penetrate small gaps in vegetation and map the ground beneath.


Large farms can utilize 3D mapping to create the best irrigation systems possible. A drone that is equipped with LiDAR only requires a single flyover to map a large field. The ability to map out potential streams to supplement the current irrigation system can improve a farm’s production immensely without increasing costs. 

Inspection of Mines

Inspections are something that drones are used frequently for whether it is inspection of a huge bridge or other piece of infrastructure. Drones with LiDAR technology have been shown to be efficient when it comes to inspection of mines. The use of drones assists miners that want to inspect a mine after it has undergone a planned detonation. These newly detonated mines are notorious for being unstable and collapsing. Drone inspection can mitigate the risk of injury for workers on-site.

Drone and mapping technology is only going to improve as the technology becomes more accessible.
