Redesigning Roadways with UAV

Company Overview

YellowScan, headquartered in Montferrier-sur-Lez, France, designs, develops, and produces unmanned aerial vehicle (UAV) mapping solutions for professional applications. Fully integrated, ultra-light, and easy to use, these highly automated data collection tools are used by customers around the world in fields such as surveying, civil engineering, mining, corridor mapping, forestry, environmental research, and archeology.

With more than 14 years of field experience, YellowScan is committed to delivering the highest level of performance, reliability, and robustness for its solutions. Their solutions are field tested all over the world in multiple environments, ranging from tropical forests to open pit mines, mountains, coastlines, rivers, and power lines.

YellowScan’s lidar solutions include the laser scanner, inertial measurement unit (IMU), GPS, embedded computer, and batteries. The processing software provided enables the generation of a georeferenced point cloud in the projection of a customer’s choice. Output formats are either .LAS (lidar industry standard) or .TXT.

YellowScan Group is a member of the Automated with Velodyne™ program.


The YellowScan UAV surveying solution needed to perform quick and easy collection of detailed data along a 47-kilometer segment of the M1 highway (E60, E65, E75) in northwestern Hungary, one of the busiest roads in central Europe.

The project was completed by Ventus-Tech, a surveying company based in Budapest, Hungary. The highway could not be closed during the project. The survey needed to be conducted with minimal interruption to traffic and completed in a short amount of time to work within an aggressive project timeline. Also, data gathered needed to present the highway environment in the highest detail, in case some aspect of the project needed to be measured in the future.

Ventus-Tech used YellowScan Surveyor, which includes Velodyne Lidar’s Puck™, to collect data along a 47-kilometer segment of the M1 highway in northwestern Hungary.


YellowScan’s Surveyor system utilized Velodyne’s smart, powerful lidar sensor technology to generate precise mapping data for this infrastructure construction project. Velodyne Lidar’s Puck™ provided YellowScan a compact and versatile sensor that delivered a high-resolution surround view image to accurately measure and analyze the highway landscape. The data, gathered by 88 UAV flights over one-month, enabled engineers to design a plan to expand the highway from 2+2 lanes to 3+3 lanes.

YellowScan Surveyor, which includes Velodyne Lidar’s Puck™, allowed Ventus-Tech to supply very detailed 3D data that accurately depicted the landscape.


Equipped with Velodyne lidar, YellowScan Surveyor improved upon previous time-intensive manual surveying processes by providing a more efficient method for collecting landscape data with increased precision and detail. It provided 100 data points per square meter with accuracy within 5 centimeters. This level of precise detail is especially important when redesigning roadways, because widening a road requires consideration of existing infrastructure, drainage networks, and vegetation.
