UAV Lidar Data Collection & Topographic Mapping

Verifiable, high-density lidar data for professionals who demand absolute precision. From penetrating dense canopy for bare-Earth DTMs to generating architectural 3D meshes, we deploy multi-return YellowScan sensors to map thousands of acres safely and efficiently.

Penetrating Dense Canopy

Lidar is the most reliable method to map the ground below a dense forest canopy.

Our YellowScan Qube240 sensor utilizes multi-echo technology. This allows the laser pulses to pass through gaps in the leaves and branches to strike the actual ground below, providing you with a true topographic map without sending a crew into the brush with machetes.

Lidar Sensors & PPK Accuracy

We utilize the YellowScan Qube 240 lidar sensor which generates 240,000 measurements per second.

Just like our imagery data, every lidar flight is anchored by our Trimble R10 GNSS network. By utilizing a Post-Processed Kinematic (PPK) workflow, we ensure every point maintains absolute global accuracy.
