LiDAR Inspection


LiDAR, which stands for Light Detection and Ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects or surfaces. In the context of drone surveys of construction sites, LiDAR is often used as a sensor mounted on a drone.

Capture highly accurate and detailed data of your site’s terrain and structures.

Data Acquisition

LiDAR-equipped drones emit laser beams toward the ground and the sensor measures the time it takes for the laser pulses to travel to the ground and back. This time-of-flight information is used to calculate the distance from the drone to the surfaces below.

Point Cloud Generation

The LiDAR sensor captures a vast number of individual points in space, creating what is known as a point cloud. Each point in the cloud represents a specific location on the surveyed surface, and these points collectively form a highly detailed and accurate 3D model of the terrain and structures.

High Accuracy and Density

LiDAR technology provides high accuracy and density of data points, making it suitable for capturing intricate details of construction sites, including ground topography, vegetation, buildings and other objects.

Vegetation Penetration

One advantage of LiDAR is its ability to penetrate vegetation and capture the ground surface beneath. This is particularly useful for construction sites with dense vegetation cover.

Mapping and Surveying

The point cloud generated by LiDAR can be used to create detailed maps, surface models, and contour lines of the construction site. This information is valuable for topographical surveys and site planning.

Volumetric Analysis

LiDAR data can be used to calculate volumes of stockpiles, assess earthwork quantities, and monitor changes in the landscape over time. This is crucial for construction project management.

Construction Monitoring and Inspection

LiDAR-equipped drones can be used to monitor construction progress, inspect structures and identify potential issues. The high-resolution data helps construction professionals make informed decisions.

Safety and Efficiency

LiDAR allows for efficient data collection over large areas, reducing the time and costs associated with traditional surveying methods. It also enhances safety by minimising the need for personnel to work in hazardous or challenging terrains.


Overall, LiDAR technology integrated with drones significantly enhances the efficiency and accuracy of construction site surveys. It provides a wealth of data that aids in planning, design, monitoring and decision-making throughout the various phases of a construction project.

I have worked with DRONE SURVEYING for some years now, from checking a boundary of new land to auditing earthworks. The use of drones on our sites is now standard; we monitor progress and calculate cut and fill via the online software as our sites progress.

Having now worked with DRONE SURVEYING engineering solutions for a number of years, their services have proven to be invaluable conducting our volumetric surveys, progress videos and cut and fill support.  The drone data platform has allowed us to get the best from the data with full support and training provided from the DS team

Jacob Henry

The drone data helps us to make quicker and smarter key decisions to ensure we have budget and time control on our projects.  Having monthly surveys on our sites ensures we keep full control of all earth movements.

Using aerial imagery from drone surveys helps us anticipate errors or mistakes in the next stage of development instead of waiting for work to start on the ground.  This proactive approach has saved us hundreds of thousands of pounds; a reactive approach can be costly
