Newsletter: Revolutionizing Land Surveys with LiDAR Drone Innovation
In 2025, the Survey Group at Fleis & VandenBrink (F&V) expanded its capabilities by purchasing a Light Detection and Ranging (LiDAR) sensor for its drone, an investment aimed at improving efficiency on large-scale surveying projects. While traditional surveying remains essential, pairing a drone with a LiDAR sensor allows the team to collect high-quality data much faster, especially on large sites. What once required days of on-foot mapping can now be completed in just a few hours.
A LiDAR-equipped drone scans the ground while in flight, shooting millions of laser points per second and capturing hundreds of data points per square meter. Traditionally, a surveyor would walk and map a grid at 50-foot intervals, noting the high and low points along the way, a much more time-consuming process.
With the speed, accuracy, and precision provided by the LiDAR sensor, mapping heavily wooded sites no longer requires our surveyors to trudge through thick brush. The LiDAR detects gaps in the tree canopy, allowing the laser to reach the ground and capture precise horizontal and vertical data. After the flight, specialized software processes the data into a detailed 3D point cloud that reveals terrain, buildings, vegetation, and other site features with exceptional clarity. This gives the survey team highly accurate information to support their reports.
