Unmanned Aerial Vehicle

Monell 3D employs the latest in UAV technology. UAV data, when integrated with accurate ground control, is ideal for our engineering clients.

Using photogrammetry software, we are able to convert the data captured in each image into accurate 3D models. Recently, we added aerial LiDAR to our services. LiDAR, similar to 3D laser scanning, generates a much denser pointcloud versus traditional UAV photogrammetry. This is ideal for collecting data hidden under a canopy or structural integrity studies.

Another advantage of using UAVs is they greatly reduce the time spent collecting accurate data. Large survey jobs that once took weeks can now be completed in just a few days. UAVs are also much safer than traditional collection methods, greatly reducing slip/trip/fall hazards and eliminating the need to survey in high traffic areas.

Previously unknown Mayan civilizations were discovered under the jungle canopy in northern Guatemala using LiDAR.

UAV projects


John Monell

“The UAV has become an essential part of data collection. On a typical landfill project, we map 100 acres an hour with a ground sampling distance (GSD) of 1 inch. The sampling is so dense that we don’t have to manually collect 3D breaklines or other key topographic features. Once the data is processed, the final 3D surface is ideal for design.”
